VIDEO SCANNING DEVICE Russian patent published in 2003 - IPC

FIELD: optical and optoelectronic engineering. SUBSTANCE: device has lens, photodetector bar, scanning mirror, scanning mirror drive, radiator bar, electronic signal processing unit, and optical projection system. Scanning mirror, photodetector bar, and radiator bar are mounted so that proportion between longitudinal dimensions of photodetector and radiator bars, between distances from photodetector and radiator bars to projection of scanning mirror axis of revolution onto its reflecting surface facing photodetector bar and reflector bar, respectively, between modulus of admissible difference in magnification of device along scanning mirror axis of revolution and that in orthogonal direction and device nominal geometric magnification given in formula of invention is satisfied.. EFFECT: provision for equal geometric magnification in both vertical and horizontal directions at minimal mass and size of device.. 3 cl, 1 dwg
