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.
Claims11
An apparatus configured to produce a hologram of an object, said apparatus comprising:
- an electromagnetic radiation assembly and an image capture assembly arranged in a single straight line optical axis, wherein the electromagnetic radiation assembly consists of one optical transforming element and one mask element along the straight line optical axis,
- wherein the electromagnetic radiation assembly is configured to:
- receive a received incoherent electromagnetic radiation from the object in an electromagnetic radiation receiving direction,
- transform the received incoherent electromagnetic radiation, in the optical transforming element and the mask element, according to a sequence of transformations including a transformation according to a complex transmission function,
- transmit a transmitted electromagnetic radiation in the electromagnetic radiation receiving direction, wherein the transmitted electromagnetic radiation is derived only from the transformed electromagnetic radiation, and
- interfere a first portion of the transmitted electromagnetic radiation with a second portion of the transmitted electromagnetic radiation, wherein both portions of the transmitted electromagnetic radiation have their axes of propagation identical to the straight line optical axis, and wherein the interference of first portion of the transmitted electromagnetic radiation with the second portion of the transmitted electromagnetic radiation occurs without intervening optical elements between the mask element and the image capture assembly;
- and
- the image capture assembly configured to:
- simultaneously capture multiple zones of the interference;
- produce the hologram of the object from the captured zones of the interference;
- and
- create from said hologram a reconstructed image of the object.
