( Source: Rice University)Scientists, including one of Indian origin, have developed a unique camera that can capture detailed images of distant objects without using a long lens, an advance that could lead to telescopes that are less bulky. The speckles serve as reference beams and essentially replace one of the two beams used to create holograms, researchers said. SAVI’s “synthetic aperture” sidesteps the problem by replacing a long lens with a computer programme the resolves the speckle data into an image, researchers said.
