摘要： A Real-Time Optical Correlating System produces holograms that contain both amplitude and phase information and have none of the time constraints of the traditional holographic methods. It has been demonstrated to operate at television field rates (60 Hz) employing currently available devices of moderate resolution. Using the System, the holographic matched filter of an input scene is calculated optically as an analog sum, captured by a charge-coupled device (CCD) camera and transmitted directly or through a computer to and displayed on a commercially available liquid crystal display (LCD) device. The correlation plane may be viewed immediately on a suitable screen because there is no film to process or computer calculations to be performed. Concurrently with the creation of the holographic matched filter of the input scene, a Fourier transform of a test scene is produced and both are imaged on another charge-coupled device camera for any correlation between the input and test scenes.

摘要： An optical correlator system for encoding a complex optical image onto a erent beam of light such as a laser and comparing it with a reference complex image. One embodiment of the invention encodes phase only information of the complex image onto the coherent beam of light by means of a liquid crystal television receiver. The light beam is passed through the liquid crystal television receiver, whose pixels are manipulated to provide phase information concerning the image. A second embodiment of the invention encodes both phase and amplitude components of a complex image onto the coherent beam of light such as a laser beam. Either or both encodings are utilized in the optical correlator system.

摘要： The spatial light modulator utilizes a modified liquid crystal television for modulating a laser beam so as to produce a transformed hologram image on a film plate which is identical with the video information being fed into the liquid crystal TV. Once a image film has been produced the film is developed and placed back in the system so that the system will now act as a comparator and tracking device. With the reference beam blocked and a new video input fed into the liquid crystal TV the system now will have an output only when the scene on the TV is identical to the scene recorded on the film. Indicator means give a signal output from this comparison that is identical.

摘要： The mirror elements mirror device spatial light modulator are selectively deflected. Such deflection causes incident infrared radiation to be reflected in selected directions. The number of deflected mirror elements as well as the degree of deflection determines the amount of reflected radiation which travels through an aperture and is collimated by suitable imaging optics, thus creating an infrared image that appears to be at infinity.

摘要： A method of and apparatus for acousto-optically addressed pattern recognition using Vander Lugt matched filtering. In optical correlation a beam of light containing an image to be examined is directed to fall on a matched filter array that contains a representation of an object of interest. Critical alignment between the beam and a matched filter of the array is achieved by acousto-optical deflection of the light beam. A large number of matched filters can be addressed sequentially at very high sampling rates, thereby providing a large memory capability for coherent optical image processing. In the system an object beam containing an image of interest is directed to a plane of interest where the matched filter is located. An acousto-optical device located in the object beam path is driven by a signal generator at megahertz frequencies. The acousto-optical device converts the megahertz frequency signals to acoustic waves that affect the density of the optical path of the object wave, changing the index of refraction at a selected plane in this path. This spatial modulation of the index of refraction across the path of the wave causes the incident light to be deflected at selectable angles. By proper selection of the megahertz frequency driving signals these variable angles are selected to direct the Fourier transform of the object beam to selected ones of an array of matched filters at the focal plane, allowing rapid correlation of any incoming intelligence information on the object beam with prerecorded information stored in a filter array.

摘要： Disclosed are a method and the chemical solutions (a blend of H.sub.2 SO..4 and CH.sub.3 COOH) employed for producing high quality crystal surfaces on CaF.sub.2 and BaF.sub.2 by a chemical polishing cycle that follows a multistage mechanical polishing cycle. The high quality crystal surfaces on CaF.sub.2 and BaF.sub.2, which otherwise are of the quality for field of use, makes these crystals ideally suited for applications as windows for HF/DF laser since the chemically polished crystal surface has fewer irregularities which reduce the amount of surface scattering of the HF/DF radiation, thus allowing a more predictable output. The high quality surfaces achieved from chemical polishing are of particular value in the study of optical absorption of very low loss materials, where the scattered radiation produces heat.

摘要： A method is disclosed by which filters are created optically in real time—and tested. This technique is made possible by recent advances in Charge Couple Detector (CCD) detector array technology. Pixel (picture element) size has decreased to the point that real fringes can be detected and displayed. The fringes result from the interference of the optical Fourier transform of a displayed scene with a specified plane wave. Phase information is thus preserved. This is the critical information required in producing a hologram or a holographic matched filter.

摘要： The off-axis joint transform correlator improves on the extant on-axis jo transform correlator by eliminating the requirement for a second laser frequency and the means for blocking the first laser frequency from propagating beyond a given point in the correlator. These eliminations are accomplished by using a beamsplitter and a mirror to bring a second portion of the first frequency at an angle to read the pattern information written onto a spatial light modulator by the first portion.

摘要： The fiber optic-based correlating and sensing system (the System) utilizes length of optical fiber through which the object beam travels prior to being incident on the holographic plate. First, a matched filter is created on the holographic plate of the initial condition of the environment. Then when the plate is re-placed in its original position in the System and the reference beam is blocked from reaching the plate, a correlation peak appears as the object beam passes through the holographic plate. To use the System as a correlator, the object beam is transmitted through an input scene prior to its travel through the optical fiber. The changes in the input scene from the initial scene causes broadening of the shape of and degradation of intensity of the correlation peak. To use the System as a sensor, the object beam travels through the optical fiber acquiring information regarding the environment surrounding the fiber, such as pressure, temperature, sound, electric and magnetic fields. Again, the changes in the environment are indicated by the broadening shape and decreased intensity level of the correlation peak.
