Scientists Develop New 3-D Camera




WASHINGTON -- Inventors in Illinois say they've developed a new type of camera that takes three-dimensional images.


The images are not holograms, which are produced with a laser beam, but can be viewed in three dimensions on a computer screen, said David Brady of the University of Illinois at Urbana-Champaign.


Brady and his colleagues developed the new camera, which takes advantage of technology known as computer tomography, or CT, which is already used to make images inside the body, and interferometry, which astronomers use to image distant objects.


The camera works by bouncing cones of white light off all points on the surface of an object and onto a sensor array hooked up to a computer program, which analyzes the pattern of light intensity to determine the exact location of each point and reconstruct the object.


The approach may provide new ways for studying cells and conducting other scientific research, the scientists write in describing the technique in the June 25 issue of the journal Science.
