| 摘要 |
The invention relates to a rangefinder that includes a laser beam-emitting device and a device for receiving the laser echoes reflected back by a target, comprising: a front optical element (10) which focuses the echoes on a detection area (5) including at least one elementary detection area (51) associated with an individual wide-bandwidth detector or time detector (42), and means for shifting the detection area towards the individual detector. The elementary area (51) is also associated with an individual low-noise detector or spatial detector (41) and the reception device also includes a switch (3) connected to the shifting means and capable of associating said elementary detection area with the time detector (42) and with the spatial detector (41) either alternately or in a static manner. |
