Device for the determination of the position of points on the surface of a body

摘要: An exploration device for the surface of a body uses laser pencil beam ch successively illuminates quasi-pinpoint regions on body. At least two distinct view taking devices are provided forming respective images illuminated region discrete element photosensitive receivers, each energized by one said supplying an electrical indication use computer to determine position region. The receivers advantageously linear in shape, example photodiode bars. Three view-taking stations equipped with these bars may be used, coordinate image computer. In order allow using comprising faulty elements, station, at identical formed elements which not coincident.
