Superman vision Ramesh Raskar

SupermanAll childhood Ramesh Raskar regretted that he did not have eyes in the back of his head. I suspect that the world does not exist if I do not look at him, so I kept turning around to see what was behind me. Although over the years this habit swirl disappeared Raskar not lost the desire to acquire a broader vision angle.

Today, as the head of the research group Camera Culture and associate professor of Media Arts and Sciences at MIT Media Lab, Raskar embodies his childhood dream into a reality, along with many others. Among his inventions – who works at the speed of light, and improvised tools for medical imaging.

What are its research objectives? I want to create not just a new way of seeing and superhuman vision, – says Raskar. He avoids the research projects that are started with a definite purpose, because you just come up with the same solution as all the others. Discoveries are usually tumbled cascades from one area to another. For example, an innovative computational method for the reduction of motion blur in photos Raskar led to the creation of new technology for analyzing how light is propagated. We are competing; what we do here can be used somewhere else, – he says.

 Inspired by the famous photograph, in which the bullet pierces the apple, created in 1964, MIT professor, Harold Edgerton, Raskar decided that he could do what he did the photographer, a million times faster. This led to one of the breakthrough discoveries of the group Camera Culture, a method of recording light in flight. By manipulating the photons in a package resembling a bullet Edgerton, a rescuer and his team were able to shoot ultra-short laser pulses through a bottle of Coke. Using a special camera to capture these pulses are recorded at a rate of half a trillion frames per second with a second exposure time.

Group traffic light photographed with wavy shadows that covered the outside of the bottle. Opened up additional opportunities and Raskar thought that this would have to create ultra-fast rendering. He was particularly interested in ambient light, like when the fog creates a visual equivalent of noise. In one experiment, Raskar able to see the object behind the wall, out of sight of the camera. Emitting ultra-short laser flashes to the nearest surface and creating millions of frames of light, like a ball bouncing across the stage, the band revealed the image of the hidden object.

She has created a camera that is capable of peeking around corners, and this invention could one day be extremely useful for mankind. The purpose Raskar make the invisible visible also applies to the human body. The camera Culture group has developed a technique of shooting eyes with tips on the phone, which led to the emergence of inexpensive and easy diagnosis of eye problems. Contemporary photographs have come a long way from a long display of instant film to digital images, and Raskar thinks the same thing happen in the field of medical imaging.

His research group is going to break all the templates and come to the forefront. Raskar sure it will happen in the next two years. Raskar also assumes that the image will serve as a catalyst for the transformation of all spheres of human life, beyond which people want to go.
