<p>The invention concerns a device for measuring a distance of a target by means of a rangefinder (1) comprising: a laser pulse transmitter (2), - a receiver (3) for the laser echoes (31) backscattered by the target, comprising a spatial detection device (10) that comprises at least one photodiode mounted as an integrator and that is capable of providing a so-called spatial signal, and a time detection device (11) that comprises at least one photodiode coupled to a transimpedance circuit and that is capable of providing a so-called time signal, - means (4) for processing the spatial signal and the time signal, comprising a unit (17) for calculating the distance of the target, the time signal being in the form of a data frame that is the recording of data detected during a predefined time period, characterised in that the processing means (4) comprise: - post-integration means (16) for the post-integration of time signals, linked at the output to the unit for calculating the distance of the target, - means (14) for selecting the time signals to be transmitted to the post-integration means, on the basis of the spatial signal, linked to the spatial detection device (10) and to the time detection device (11).</p> |
