In the field of deviometers used for detecting and locating laser spots, and more precisely to a laser spot detector with matrix deviometer, a device comprises a readout circuit exhibiting a matrix of pixels, a matrix of photodiodes produced on a single substrate, said photodiodes each comprising an individual electrode, and a laser pulse detection device. The particular feature of the device resides in the fact that said matrix of photodiodes is hybridized on said readout circuit by way of balls made of flexible and conducting material, such as indium, placed in contact with the pixels of the readout circuit, so that said single substrate constitutes an electrode common to the set of photodiodes and that said individual electrodes are linked to said pixels by said balls.

The invention relates to a pixel of a CMOS imager, the pixel comprising:

Pixel of a CMOS imager of an optical detector

The invention relates to a range finding method for a target by means of a pulsed laser () and a device for detecting pulses backscattered by the target, which comprises a step for emitting pulses with a repetition frequency f. The detection device comprises an array of photodiodes () associated with integrators (). The method comprises steps for roughly then finely locating the target, the rough locating step comprising the following substeps:
