ABSTRACT:
Optical imaging of an object utilizes a plurality of amplitude modulated light rays propagating through the object, either sequentially or simultaneously, for detection by a single photodetector. The light rays may propagate geometrically (i.e., directly) or diffusively. Each of the rays is encoded with a different phase to provide sufficient information for decoding the light intensity detected by the photodetector. The rays may be applied simultaneously in an array, in which case different carrier frequencies as well as different phases are applied to the different rays by any of a number of modulators. Alternatively, the rays may be individually applied to the object in a sequence of phase encoded rays. In either case, the single photodetector receives sufficient information to image each of the voxels of interest in the object being imaged. Information may be obtained for different voxels selected for imaging without mechanical scanning.
