摘要： The twin-image elimination apparatus of the present invention comprises (a) a scanning light source for emitting a scanning light beam; (b) an interference device which converts the scanning light beam from the scanning light source into a spherical wave and a plane wave having temporal frequencies different from each other and combines the spherical and plane waves together; (c) a scanner for scanning an object with the combined light beam from the interference device; (d) a photodetector for detecting a scattered wave from the object; (e) a first multiplier which converts an output signal of the photodetector into a cosine-coded holographic information; (f) a second multiplier which converts the output signal of the photodetector into a sine-coded holographic information; and (g) a holographic reconstruction device which converts output signals of the first and second multipliers into a sum signal, in which these output signals are added together with a phase difference of .pi./2+2n.pi. (wherein n is an integer not less than 0), so as to reproduce an image of the object without the presence of its twin image. Hence, at the time of reconstructing a hologram, the virtual image component contained in the output signal of the photodetector can be removed, thereby improving the image quality of the reconstructed image.

摘要： A three dimensional true color holographic imaging system using three primary color Fresnel-Zone-Pattern laser generators combined as a single beam that scans the target and the reflections of which are sensed simultaneously by a single electronic detector. The detector signals corresponding to each generator are then separated electronically and independently recorded.

摘要： An optical scanning holography system which requires only a two dimensional scan to record three dimensional information from a fluorescent specimen wherein the optical scanning holography is based on scanning the specimen with a Fresnel zone pattern and detecting and decoding the fluorescent light reflected from the specimen. The flourescent light reflected from the specimen contains three dimensional information about the specimen so that once the fluorescent light is detected and decoded a three dimensional image of the specimen can be obtained and displayed using only the two dimensional scan.
