| 摘要 |
The invention relates to a device for optical distance measurement, in particular a device functioning in accordance with the phase measurement principle, having at least one transmission unit ( 12 ) equipped with at least one light source ( 22, 24 ) for transmitting modulated optical measurement radiation ( 16 ) toward a target object ( 20 ), and having a reception unit ( 18 ) for receiving the optical measurement radiation ( 17 ) returning from the target object ( 20 ). According to the present invention, the device has means ( 51, 55, 68 ) that enable a measurement of distances from a target object ( 20 ') by means of a triangulation method. The invention also relates to a method for optical distance measurement in which it is possible to switch back and forth between a phase measurement method for determining a distance of a distance measuring device from a target object ( 20, 20 ') and a triangulation method for determining this distance.
