Abstract
The invention relates to time of flight telemetry and has application to detection and imaging systems. Determination takes place of a response time of an optoelectronic measuring chain or cascade (20, 34, 36) able to measure an outward and return time (flight time) of a first light pulse emitted in the direction of an object whose distance is to be determined. This response time, determined by means of a second light pulse emitted and then detected by the measuring chain or cascade, is subtracted from the previously determined outward and return time in order to obtain a corrected time used for calculating the sought distance.
