| 摘要 |
<p>The invention relates to a distance measurement sensor comprising
at least two optoelectronic signal sources (10, 12) for projecting at least two spots (22, 26) on a target (24),
an optoelectronic receiver (30),
an optics (14, 32) for reproducing the at least two spots (22', 26') on the optoelectronic receiver (30), and
means (44, 46, 48, 50, 52) for processing the output signals (I1, I2) generated by the optoelectronic receiver (30) and for controlling the at least two optoelectronic signal sources (10, 12) depending on the processed output signals (I1, I2) in order to measure the distance between the target (24) and the sensor by a triangulation technique.</p> |
