System, apparatus and method for extracting three-dimensional information of an object from received electromagnetic radiation

Abstract

An apparatus and method to produce a hologram of an object includes an electromagnetic radiation assembly configured to receive a received electromagnetic radiation, such as light, from the object. The electromagnetic radiation assembly is further configured to diffract the received electromagnetic radiation and transmit a diffracted electromagnetic radiation. An image capture assembly is configured to capture an image of the diffracted electromagnetic radiation and produce the hologram of the object from the captured image.

1 . An apparatus configured to produce a hologram of an object, said apparatus comprising:
 an electromagnetic radiation assembly consisting of one diffractive electromagnetic radiation element and configured to receive a received electromagnetic radiation from the object and transmit a transmitted electromagnetic radiation based on the received electromagnetic radiation; and   an image capture assembly configured to capture an image of the transmitted electromagnetic radiation, and produce the hologram of the object from the captured image, wherein the electromagnetic radiation assembly is configured to control only a phase of the transmitted electromagnetic radiation.
