A device for detection of the spot laser wheel matrix.

摘要

The present invention lies in the field of the deviation measurers used for the detection and location of the laser spots, and more specifically relates to a detector of the laser spot on the deviation measurer matrix. The device according to the invention comprises a read circuit (roic) with a matrix of pixels (int), an array of photodiodes (ph) made on a single substrate (s), said photodiodes (ph), each comprising an individual electrode, and a detection device of the laser pulse (d). The particular feature of this device resides in the fact that the said array of photodiodes (ph) is hybridized on the reading circuit (roic) by means of a ball (b) made of flexible material and the conductor, such as indium, placed in contact with the pixels (int) of the read circuit (roic), so that the said single substrate (s) constitutes an electrode common to all the photodiodes (ph) and that the individual electrodes are connected to the pixels (int via said balls (b)).
