WebThe basic theories of incoherent propagation [15] allow much more efficient ways to generate For visible-light communications, LEDs are typically used beam-steering holograms, by removing further propagation as optical sources for both illumination and communication after the hologram plane. WebWe present a lensless, interferenceless incoherent digital holography technique based on the principle of coded aperture correlation holography. The acquired digital hologram by this technique contains a three-dimensional image of some observed scene. Light diffracted by a point object (pinhole) is modulated using a random-like coded phase mask ...
