Gabriela Barreto Lemos – Quantum Photography – Brazil

Quantum photography technique that allows you to record images without light passing through the object.

Typically, a beam of light interacts with an object; In this same beam, the image of that object is formed, which is recorded on a camera, on paper or directly into the eye. This research used two quantumly entangled photon beams. An infrared photon was directed at a silicon wafer engraved with the image of a cat. The other photon, red, was sent on a different trajectory, did not pass through the silicon plate and was detected by an EMCCD (electron-multiplying charge-coupled device – a photographic camera with sensitivity to very low intensity light). The image of the cat engraving was recorded by the camera, which only detected the red light, which did not touch the engraving. It is the first time that an image has been captured in a beam of light that has not interacted with the object that produced the image.

The experiment, led by researcher Gabriela Barreto Lemos, was carried out at the Institut für Quantenoptik und Quanteninformation in Vienna, 2014.

The technique has potential for applications in indirect image capture, from medicine to quantum computing.

“Espills” is a solid light dynamic sculpture. Built using laser beams, laser scanners and robotic mirrors, it is inspired by crystalline formations. A set of geometric figures that float in the air and which suggest, in an abstract way, the transmutation of matter from chaos to order. Dust becoming crystal, being eroded and becoming sand again.

MOBILITY
THE INSTALLATION SPANS A CORRIDOR OF 7-METRES WIDTH. ON THE LEFT WALL ONE HUNDRED PROSTHETIC HANDS ARRANGED IN A MATRIX REVOLVE AROUND THEIR OWN VERTICAL AXIS, THE MOVEMENTS BEING CONTROLLED BY MOTORS. THE MIRRORS THEY HOLD REFLECT THE BEAM OF A STRONG LIGHT ACROSS THE SPACE AND ONTO THE OPPOSITE WALL. WHAT INITIALLY SEEMS LIKE AN ASYNCHRONOUS, CHAOTIC PATTERN OF MOVEMENT SOON REVEALS ITSELF AS A COMPLEX, COMPUTATIONAL

流动性
该安装跨越了7米宽的走廊。在左墙上，排列成矩阵的一百个假肢手绕其自身的垂直轴旋转，其运动由电动机控制。他们持有的镜子将强光光束反射穿过整个空间并射向对面的墙壁。最初看起来像是一个异步的，混乱的运动模式，很快就显示出一种复杂的计算编排：首先，一百个光点围绕一个中心点移动，类似于行星的天体动力学或昆虫群的飞行模式。并创造出三维空间的印象。然后突然之间，这种有机振动会聚成一个表示运动和动作的汉字。

Cloud Arbor
A 20-foot diameter sphere of fog forms inside a forest of stainless steel poles. High-pressure fog nozzles embedded in the 30-foot tall poles convert water into a cloud that appears and vanishes every few minutes. A collaboration with landscape architect Andi Cochran and the Pittsburgh Children’s Museum. Completed in 2012.

Rising Awareness
Could one succeed in rising the level of awareness by sharpening one’s perception rather than repeating the vapid catchphrase, “raising awareness,” which has been coopted by an ever-growing money-raising industry that fails to improve our circumstances in a substantive way? Wearing a cocktail dress, I assembled a large kinetic structure made of wooden beams and ladders in front of the audience. I then walked and balanced on the twenty-foot wide structure at eight feet off the floor. Rising Awareness addresses my ongoing preoccupations about the physicality of experience, inhabiting the body, proprioception as the possible strongest sense of self, how spatial awareness correlates with overall awareness and self-awareness, how physicality enhances creativity, finding balance between gravity and groundlessness, a concept of happiness as the fullest expression of one’s particular cognitive potential, pushing boundaries, and the current irreverent politics of liability.

Between I you I and I me
BETWEEN | YOU | AND | ME is a wall of sound and light. Like any other wall, it defines an architectural space. Given its ephemeral, dynamic media – ultrasound and beams of light – the wall can be perceived only when the visitor comes close and interacts with it. Two thin membranes of light form a visible frame filled with sound. Multichannel, extremely vectored hypersonic speakers render audible various textures of broken glass: a sound architecture within the wall, comprised of juxtaposed single sound beams, whose constellation changes depending on the visitor’s position. Observed from a distance, the wall fades away: clear transparency and only faintly resonant tones attest to its non-existence.

sound cloud
London-based designer kazuhiro yamanaka has created the ‘sound cloud’ a light-emitting quantum glass speaker system installation for saazs ‘a glass house’ program. the structure is composed of five interactive monolithic glass panels, formed with the intention of modelling the integration of innovative glass within architecture and design. the sound and light radiating from ‘sound cloud’ shift in unison, their synchronization may be altered by the viewer as they adjust their aural and visual experience by means of a touch-screen controller.
yamanaka aspired for the visitors to ‘be able to hear the sound move from one to another, jumping back and forth and echoing from the panels.’
a sound module is attached to each panel. as it vibrates,the three layers of glass move at a frequency, which creates optimum sound quality. the sound for the installation was developed by the france-based sound designer, gling-glang. yamanaka and gling-glang devised a soundscape by which ‘sound cloud’ visitors were able to sense the sculptural construction of the music in walking through the installation’s glass-paneled pathway.
the glass is outfitted with a light-emitting system known as ‘LED in glass’, invented by quantum glass. through this technology, the panels become a source of light. the ‘sound cloud’ is illuminated as the LED bars are fitted around the edge of the panel in order to direct beams of light through the edge of the extra clear glass sheet. as a result, light refraction occurs from the front side by means of a white enamel screen print on the opposite side.
yamanaka chose to slightly obscure the brightness of the glass sound system by creating a thin layer from millions of light dots, culminating in a cloud-like shape.

Harmonics
Harmonics challenges our perception of light and sound unfolding at great speed, an illusion of time blending. As the two kinetic sculptures speed up, rotating beams of light blend to form volumes of colour, while multiple discrete sounds become a major chord. Unable to process extremely fast information, our brain reads sequential sensory inputs as a single event in time. A disconnected reality perceived as a continuum, a harmonious whole.

7.0
Audio visual installation with sound and seven spinning motorized laser mounted on rotating bars. As the bars spin, the straight-line laser beams spread into a cylinder and cone-shaped sculptures. The inclination and position of the laser changes the geometry.

Halo
99 robotic mirrors continuously move throughout the day to follow the sun like sunflowers. These mirrors, arrayed across two 5 meter tall towers and one 15 meter long track, each emit a beam of sunlight into a cloud of water mist. The beams are computationally aligned so that together they draw a bright circle in the air. Dependent entirely on the presence of the sun for its completion, the work explores the possibilities and limitations of technology to capture what is out of reach, to harness nature and bring the sun down to earth. Collaborating with the natural fluctuations in the climate, Halo appears only for moments when the wind, sun, water, and technology coincide, creating a form which exists between the material and immaterial.

Orbit
Orbit is a kinetic light installation designed for a former railway tunnel. A series of rotors of increasing diameter and speed are positioned along the 80m space, projecting laser beams into the void. Their orbiting constellation targets towards a circular plane at the end of the tunnel.

キムチアンドチップス
Light Barrier
Kimchi and Chips create phantoms of light in the air, crossing millions of calibrated beams with their work Light Barrier, 2014. The light installation creates floating graphic objects which animate through space as they do through time.

Moving footbridge
Paddington, London
Opening in sequence, the bridge’s five beams rise to different angles to create a fan-like effect. The first rises to 70 degrees, while the last lifts high enough to create a clearance space of two and a half metres over the surface of the canal. The weight of the beams – which range from six to seven tons – is balanced by a 40 ton counterweight that keeps the beams steady as they rise and fall.

Convergenze parallele

Convergenze parallele is an audiovisual installation in which airborne dust particles passing through a beam of light are tracked, visualized, and sonified in realtime by a custom software system. The installation reacts to air movements in the exhibition space, allowing the viewer to see and hear the amplified movement of dust particles. “Convergenze parallele” explores the poetic potential of revealing and transforming the imperceptible. The custom software uses a video camera to capture the activity of dust articles passing through the beam of light. It then analyzes the video signal to track the location of individual dust particles, and reveals each particle’s trajectory in the image-processed projection. The physical particles draw traces of their otherwise invisible motion on the digital screen. At random intervals, the software artificially saturates the system by briefly activating the fan-a cloud of dust fills the beam of light and creates dense and stunning patterns of particle trajectories and sound.

Tate Project Part I ]
The choreography rehearsed and performed in 2010 paired the rigour of classical steps with contemporary movement, a juxtaposition that paralleled Clark’s training as a ballet dancer at the Royal Ballet, and his later anti-hierarchical, anti-authoritarian choreographic experiments. Balletic poses, jumps and steps were isolated from traditional narrative sequences and made strange through repetition. The graceful leaps and turns of the trained dancers seemed awkward and uneven, just as they were often out of sync and oriented in different directions. This choreography paralleled the performance space, which was demarcated by geometric and striped floor mats designed by Charles Atlas, which resembled the large windows at the back of the hall and the black beams that extend vertically from floor to ceiling.

Re-projection: Hoosac

Influenced by the utopian projects — and notable failures — of innovative artists and designers such as Buckminster Fuller, Frederick Kiesler, and Charles Eames, Tobias Putrih likens his works to experiments, or design prototypes. His use of cheap materials, including egg crates, cardboard, and plywood signify both a sense of potential and impending collapse. Many of the artist’s works reference the architecture and spectacle of the cinema: a space suspended between fantasy and reality, image and environment. With Re-projection: Hoosac Putrih distills the cinema to its most basic element: fishing line stretched across the gallery mimics the conical trajectory of a beam of light. A spotlight hits the strands of monofilament which in turn become a screen, reflecting an image in illuminated dots. Inspired by the Hoosac Tunnel just east of North Adams — a storied, engineering marvel that draws ghost-hunters to the area — Putrih’s tunnel is, likewise, both real and a representation, an optical trick that invites both wonder and investigation.

BARACK OBAMA: NEXT INDUSTRIAL REVOLUTION
This monumental 3D Printed sculpture is the three-dimensional materialisation of President Obama’s voiceprint. The 3D voiceprint portrays an extract of President Obama’s February 2013 State of the Union Address. It represents the materialisation of the very thoughts and words of the President of the USA. The sculpture is interactive. A movement sensor activates the system and a laser beam scans the 3D recording to reveal the President’s words and message. The work was printed using a 3D desktop printer and the housing designed by Patrick SARRAN.

The Harmonic Series

File Festival

Created by Manuela Donoso and Luisa Pereira, The Harmonic Series is a collection of mechanical devices , software, sculptures and prints that explore the relationship between musical and visual harmony.Inspired by the nineteenth century mathematician Jules Lissajous who invented a device to visualize sound vibrations using two tuning forks and a beam of light reflected from one mirror to the next to a screen, Manuela and Luisa have re-created and extended this experiment using recent tools. An electronic version of the device replaces the tuning forks with microphones and speakers, allowing people to sing different musical intervals, and contrast the resulting figures with the more chaotic ones generated by percussive sounds. An application plays groups of three notes and plots 3d Lissajous figures for their frequency ratios. The frequency ratios for major, minor and diminished chords are 4:5:6, 10:12:15 and 20:24:29 respectively. These chords were plotted using the app, and then printed as posters and sculptures that reveal a tight relationship between aural and visual harmony.

Furthering his technological trend, Chalayan unveiled the collection entitlledReadings, on screen, eshewing the conventional runway. The dresses themselves are highly structured, creating bold silhouettes from which the laser beams radiate. They are embellished with Swarovski crystals that either deflect the lasers, or take in their light, depending on the angle of the laser. The effect is hauntingly beautiful; where lasers shine directly into Swarovski crystals, they resemble glowing embers, yet where they are deflected the laser beams project into the surrounding space, evoking phantasmagorical new-age sun gods.
