摘要： A method and apparatus is disclosed for stabilizing the operative angle of acceptance of a multiple-beam interferometer means that is employed in an optical measuring system wherein optical radiation source means are employed. In accordance with the disclosed apparatus, the optical radiation source means is utilized to provide a reference point optical radiation source which emits reference optical radiation that is received by the multiple-beam interferometer means. With respect to such reference optical radiation, a set of reference non-localized multiple-beam interference fringes are created by the interferometer means. A photoelectric detection means is provided to detect the two-dimensional position of at least a portion of the innermost interference fringe of the reference set of interference fringes. Such positional information is transmitted by electrical signals to a processor means which compares such signals to desired values therefor. The desired values reflect what size said detected innermost fringe should be if the multiple-beam interferometer means is operating at a predetermined and desired angle of acceptance. If deviations from such desired values are discerned by the processor means, the processor means will transmit a control signal to the optical radiation source means. The control signal will instruct the optical radiation source means to vary the wavelength of the radiation emitted thereby so as to cause the operative angle of acceptance of the interferometer means to stabilize about the desired value therefor.

摘要： A cathode ray tube display system and method having bidirectional line scanning are disclosed. Bidirectional line scanning is achieved by scanning each odd numbered scan line from left to right and each even numbered scan line from right to left, thereby avoiding the necessity for retrace, or flyback. In order to avoid loss of intelligibility in displaying the video information received from a conventional source providing video information written only from left to right, as is conventional, the received video information is stored in memory by scan lines with each odd numbered line being read out in the same order as stored in memory and each even numbered line being read out in reverse order as stored in memory. Timed control is provided for processing of the video information and display thereof with bidirectional scanning, and geometric error correction is provided for both the horizontal and vertical scan generators.
