  • Digital system for generating laser-modulation multi-channel circuit control signals for an oscillating mirror projector of scanned images
    Patent number: 4931874
    Abstract: To compensate for the non-linearity of the oscillations of the line galvanometer of a scanned image projector with oscillating mirrors, compensation circuits are used. These compensation circuits act on the video signal by modulating the duration of the pixels of the digitized video signal and their position in the period of the line, in a manner that is inversely proportionate to the instantaneous speed of the galvanometer. The system can be applied to fighter aircraft simulators.
