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 configured to receive a received electromagnetic radiation from the object along a radiation axis in an electromagnetic radiation receiving direction, transmit a transmitted electromagnetic radiation along the radiation axis in the electromagnetic radiation receiving direction, and interfere a first portion of the transmitted electromagnetic radiation with a second portion of the transmitted electromagnetic radiation the transmitted electromagnetic radiation; and   an image capture assembly configured to capture an image of the transmitted electromagnetic radiation transmitted along the optical axis in the electromagnetic radiation receiving direction, and produce the hologram of the object from the captured image,   wherein the radiation axis is a straight line.
