OPTOELECTRONIC DEVICE FOR OBSERVING AND/OR AIMING AT A SCENE, COMPRISING A RANGEFINDER, AND RELATED RANGE-FINDING METHOD

The invention concerns an opto-electronic device for observing and/or aiming at a scene comprising a target (C), comprising an observation module (1) comprising an image sensor (10) and a stabiliser (11) for a line of sight (100) towards the target (C); and a telemeter (2) comprising a multi-shot pulsed laser (20) for emitting a plurality of outward laser pulses (An) in the direction of the target (C) to be telemetered, and a detector (21) for a plurality of return laser echoes (Rn) reflected by the scene in order to generate an electrical signal for each return laser echo (Rn) in order to effect a measurement of the distance to the target (C), each return laser echo (Rn) corresponding to an outward laser pulse (An); characterised in that it also comprises a sensor (3) of angular movement of the device with respect to the stabilised line of sight (100) in order to determine an angular radius (rhon) of each outward laser pulse (An) with respect to the stabilised line of sight (100); and a selector (4) for processing each electrical signal, corresponding to a return laser echo (Rn), according to the angular radius (rhon) of the corresponding outward laser pulse (An). The invention also concerns a telemetry method implemented on such a device.
