A new position-sensitive photodetector (PSPD) for photoelectric transducers of rotation angle is described, which is based on a three-layer ring sector structure. The output voltage of the PSPD is a linear function of the angle of rotation of a light-emitting diode relative to the PSPD contacts. The proposed device is highly reliable and ensures angle determination to within 7 min of arc. Rotation-angle transducers based on this PSPD are compatible with any measuring, matching, and processing equipment.
