  • Optical system with test/calibration
    Patent number: 5859429
    Abstract: Optical systems are provided. In one embodiment, the optical system includes a detector for detecting a light signal. A light signal gatherer and guider is optically connected with the detector for gathering the light signal and guiding the light signal to the detector. The light signal gatherer and guider has a check signal entrance location disposed along an outer surface of the light signal gatherer and guider. A check signal source is optically connected with the light signal gatherer and guider so that a check signal generated by the check signal source randomly illuminates the check signal entrance location on the outer surface of the light signal gatherer and guider.
