Abstract:
1. A device for optical distance measurement 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 ), wherein the device has means ( 51 , 53 , 55 , 68 ) that enable a measurement of distances between the device and a target object ( 20 ′) using a triangulation, wherein the means include the light source ( 22 , 24 ) of the transmission unit ( 12 ).
