Optoelectronic adjusting aid for adjusting optical structures, e.g. light barriers esp. photo diodes

摘要

The adjusting aid consists of a multiple of photo sensors (1-4), esp. photo diodes, which are arranged preferably symmetrically on a substrate. The signals of the photo sensors are called up for the determining of the optical centre of gravity of the incident light, which is compared with a desired position (12). Depending on the position of the optical centre of gravity, illuminating one or more optical signal transmitters (6-10) such as LEDs to a different brightness. An information concerning this position is optically transmitted, so that the incident light beam can be so corrected, that it finally coincides with the desired position on the adjusting aid.
