Abstract: 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.

Abstract: The invention relates to a pixel of a CMOS imager, the pixel comprising: an infrared photodiode suitable for generating an electric current when it is exposed to an optical radiation having a wavelength greater than 950 nanometers, a conversion circuit able to receive electrons and deliver a voltage with a value varying as a function of the number of received electrons, a first switch connected between the infrared photodiode and the conversion circuit.
