Abstract

The optical system of a new type of high-precision compact turning-angle sensor based on a BR-180° prism and a photoelectric autocollimator is considered. Measurement errors of the sensor that occur owing to a disturbance in its geometrical layout were estimated. How this optical system can be used to create a sensor for determining the triaxial orientation of one object relative to another is demonstrated.
