Abstract

The invention relates to a method for increasing the light produced by a laser beam on a target, consisting in reflecting this beam on a deformable mirror comprising several piezoelectric elements. The polarization voltage of each of the elements is successively increased by a predetermined DC voltage, this increase being maintained only if it corresponds to an increase in the light intensity diffused by the target. Application to the focussing of a data transmitting laser beam on an aerial.
