Optoelectronic position monitoring system for use on road vehicle uses laser scanner and sensor module with mirror set at angle on shaft with calibration disk driven by electric motor

摘要

The mirror (47) is set at an angle of 45 degrees on a shaft (17) with a calibration disk (51) adjacent to a reader (53). The shaft is rotated by an electric motor (21). There are two pulsed lasers (11), each with its own lens (33) on either side of a big lens (35) for the light receiver (15) array (59). The receiver array is positioned at the bottom of a shaft (55) and has an optical filter (57) in front of it. The system includes an evaluation circuit (25) and a control circuit (27) and has a connection (63,65) to a computer (67).
