System, apparatus and method for extracting image cross-sections of an object from received electromagnetic radiation

Abstract

An apparatus and method to produce a hologram of a cross-section 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 cross-section of the object from the captured image. The hologram of the cross-section includes information regarding a single cross-section of the object.

1 . An apparatus configured to produce holograms of plural cross sections of an object that emits an emitted electromagnetic radiation, said apparatus comprising:
 an electromagnetic radiation assembly different from the object, said electromagnetic radiation assembly configured to receive the emitted electromagnetic radiation from the object, diffract the received electromagnetic radiation, and transmit a diffracted electromagnetic radiation;   an image capture assembly configured to capture at least one image of the diffracted electromagnetic radiation, and produce holograms of plural cross-sections of the object from the at least one captured image, each of the holograms including information regarding a single cross section of the object, and   a varying device configured to vary a distance between the object and at least one component of the electromagnetic radiation assembly, wherein   the electromagnetic radiation assembly is between the object and the image capture assembly.
