Abstract
This laser telemetry device operating on the principle of the measurement of the transit time of a light pulse, is characterized in that it comprises: PA0 a passive switching microlaser (2), PA0 means (6, 10) for receiving a light pulse (18, 19) reflected by an object (4) and for the detection of the reception time of said pulse, PA0 means (8, 10) for the detection of the emission time of a pulse from the microlaser (2), PA0 means (12) for measuring the time interval or slot separating the microlaser pulse emission time and the reflected beam reception time.
