The invention relates to an optical angle measuring device (1) for electromagnetic radiation, such as laser light. The angle measuring device exhibits no moving parts and can be made compact. According to the invention, means (2,6.1,6.2) are provided for dividing the incident radiation into at least two radiation parts. A detector (7.1,7.2) is allocated to each respective radiation part. The angular position is calculated on the basis of signal strengths output by the detectors (7.1,7.2) by calculating ratios between difference signals and sum signals for signal strengths of the detectors, which ratios correspond to predetermined angular positions. <IMAGE> |
