Constructive and reconstructive of holography
WebThis study demonstrates that 3D samples, including 3D phase objects, can be reconstructed from two or more holograms. It is shown that in principle, two holograms are sufficient to recover the entire wavefront diffracted by a 3D sample distribution. WebJun 28, 2024 · The technique of producing a three-dimensional image of an object is called holography. The photograph showing the three-dimensional image of an object is called holograms (holos is the Greek word means ‘whole’). This technique becomes familiar after the invention of a highly coherent light beam of the laser. Danish Gabor was awarded the ...
