摘要:
In a position detection system when a preselected parameter magnitude of a signal produced in response to a received reflected laser beam, is excessively high, the power of the laser is reduced until such a satisfactory level is reached. On the other hand when the signal level is low and laser power cannot be increased further, signal amplification is induced until such time as the required level is produced.
