ABSTRACT:
A parallel-to-serial converter is described for use in translating a plurality of parallel line scan signals, derived from scanning a scene, to a serial signal suitable for application to a conventional television-type raster-scan display device. The parallel analog signals from a linear array of photodetectors scanned across a scene are simultaneously clocked into an equal number of charge coupled device (CCD) registers. The stored signals are later read out serially line-after-line and applied to a television type display. Two arrays of CCD registers are provided so that one can be loaded while the other is being read out. Each CCD register for a given line of video information consists of two parallel registers which alternate in receiving (and supplying) signals representing successive elemental areas along the line of the scene.
