Abstract
The present invention relates to a range-finder comprising a laser pulse emission device and a device for detecting the pulses reflected by a distant object.The emission device is capable of emitting pulses of N distinct wavelengths, N being an integer greater than 1, with, for each wavelength, a pulse repetition frequency less than a predetermined threshold frequency.Thus, no given wavelength emission will be faced with the problem of distance ambiguity.
