DEVICE FOR OPTICAL-MECHANICAL SCANNING OF IMAGES BY MEANS OF CORNER REFLECTORS

摘要

Device for optical-mechanical scanning of an image using a detector comprising a rotatable drum filted with corner reflectors in order to transform optical signals from different image points into corresponding electric signals by means of a transformer, the corner reflectors consisting of three reflecting surfaces, pairwise forming essentially right angles with one another and so arranged that the three reflecting surfaces converge in a three-dimensioned, essentially right-angled corner having the reflecting surfaces inside the corner.
