Abstract :
In former developed systems, high precision measuring of the angle of incidence of a light source can be obtained only in surroundings without ambient light. In this paper an enhanced method based on a previous system is presented. This method additionally allows precise measurements in environments with any ambient light conditions. So high precision angle measuring in industrial standard surroundings is not critical anymore.
