<p>The invention relates to a method for detecting laser pulses having a repetition period T1 with an amplitude jitter tj, detected using a matrix of photodetectors, said method including the step of integrating charges in a predetermined duration ti and according to a period Tm larger than a minimal period Tmin. The detection is carried out sequentially in the following manner. 1 : detection of a signal having the time characteristics of the expected laser code using the matrix and without using an auxiliary sensor; this phase involves using an integration period equal to the smallest submultiple of Tl+ti-tj larger than Tmin, wherein ti is the matrix integration duration and Tmin is the minimal integration period. 2 : confirming the detection of this first pulse and detecting the following laser pulses; this phase involves using an integration period T1' which is different from the period T1 of the pulses outputted by the laser due to the closing speed between the pulse generator and the matrix. The method can be used for detecting laser pulses without using an auxiliary sensor as the matrix becomes an autonomous pulse detector.</p> |
