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

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 location of the input object focal plane or a location of the output focal plane for each of the single cross sections of the object, wherein
• the electromagnetic radiation assembly is between the object and the image capture assembly.
