Abstract
A device for measuring a distance of a target by means of a telemeter comprises: a laser pulse emitter; a receiver of the laser echoes backscattered by the target, comprising, a spatial detection device which comprises at least one photodiode set up as integrator and is able to provide a spatial signal, and a temporal detection device which comprises at least one photodiode coupled to a transimpedance circuit and is able to provide a so-called temporal signal, means of processing of the spatial signal and of the temporal signal, comprising a unit for calculating the distance of the target, the temporal signal being in the form of a data frame which is the recording of data detected over a predetermined duration. The means of processing comprise: means of post-integration of temporal signals, linked at output to the unit for calculating the distance of the target, linked to the spatial detection device and to the temporal detection device, means for selecting the temporal signals to be transmitted to the post-integration means, as a function of the spatial signal.
