Patent ID: 8405890

Claim:
An apparatus configured to produce a hologram of a cross-section of an object, said apparatus comprising: an electromagnetic radiation assembly configured to receive a received electromagnetic radiation from the object and transmit a transmitted electromagnetic radiation based on the received electromagnetic radiation, the transmitted electromagnetic radiation including the hologram of the object; and an image capture assembly configured to capture an image of the transmitted electromagnetic radiation and produce the hologram of the cross-section of the object from the captured image, the hologram of the cross-section including information regarding a single cross-section of the object, wherein the electromagnetic radiation apparatus includes a diffractive electromagnetic radiation element or two lenses configured to produce an off-axis Fresnel Zone pattern when the two lenses are illuminated by a coherent light. wherein the electromagnetic radiation apparatus includes a diffractive electromagnetic radiation element or two lenses configured to produce an off-axis Fresnel Zone pattern when the two lenses are illuminated by a coherent light.
