HOLOGRAPHIC IMAGE GENERATION AND RECONSTRUCTION

摘要

Technologies are generally related to holographic imaging. In some examples, techniques are described for generating a holographic image of an object using a plurality of light sources, a shutter, and an image sensor array. Each of the light sources is configured to generate a light beam using a respective wavelength in a different range. In various examples, an apparatus as described here may be configured to control the shutter to receive the light beams from the plurality of light sources and selectively pass each of the received light beams to provide a selected light beam. The apparatus may further include a beam splitter and a mirror unit configured to generate an object light beam and a reference light beam from the selected light beam. The apparatus may include an image sensor array configured to detect an image of interference caused by the reference light beam and the object light beam.

1. An apparatus configured to generate a holographic image of an object, the apparatus comprising:
a plurality of light sources, each configured to generate a light beam corresponding to a wavelength in a different range; a shutter configured to receive the light beams from the plurality of light sources and selectively pass each of the received light beams in turn to provide a selected light beam; a beam splitter configured to split the selected light beam into a first light beam and a second light beam, wherein the beam splitter is also configured to irradiate the first light beam on the object such that at least part of the first light beam is scattered by the object to generate an object light beam; a mirror unit configured to receive the second light beam from the beam splitter, and return at least part of the second light beam as a reference light beam; an image sensor array configured to receive the reference light beam and the object light beam, and also configured to detect an image of interference caused by the reference light beam and the object light beam, wherein the image sensor array comprises an array of sensors configured in a shape of either a cylinder or a polygonal prism that substantially surrounds the object; and a video signal generator unit configured to convert the detected image into an image signal associated with each of the plurality of light sources.
