Body`s e.g. shaft, spatial position determining device, has set of opto-electronic line sensors provided for direct or indirect determination of points of impact of ray of light expanding in two or more levels

摘要

The device has a device (130) e.g. receiver, for sending light rays or laser, where the light rays expand in two or more levels and include a cross wire or star shaped cross section. A set of opto-electronic line sensors (42, 43, 52, 53) is provided for the direct or indirect determination of points of impact of the ray of light expanding in two or more levels. The line sensors are arranged on sides of quadrate.
