A photodetection device including at least one element incorporating a radiation absorption layer and an unabsorbed radiation reflection layer. The absorbing layer creates a first phase shift of the reflected radiation compared with the incident radiation. According to the invention, between the absorbing layer and the reflecting layer a layer is provided creating a second phase shift, which compensates the first phase shift for obtaining a substantially flat spectral response of the device.

Process for the exchange of a detection module hybridized by welding

The device includes at least two abutting detection elements (16, 18) having, on one face, a plurality of photodetectors (22, 24). A complementary detection element (26) has, on one face, a plurality of detectors (28) and is positioned astride the two abutting elements. The photodetectors of said complimentary element are positioned facing the faces of the two abutting elements and have no photodetector facing the photodetectors of the complementary element. The invention is useful in thermal imaging.

Electromagnetic radiation detector and its production process. The detector comprises a thin detection material film (8), which is sensitive to the radiation to be detected and which has a first and a second faces (10, 12), the first face being directly exposed to the radiation to be detected, a resin coating (18) surrounding the thin detection material film (8) and having a lip (20) which projects beyond the first face (10) of the thin film (8).

Electromagnetic radiation detector and its production process

A three-dimensional radiation detection device incorporates a detection array (22) receiving the radiation and supplying signals representing the latter, a circuit for reading these signals comprising a block (24) having at least one stack of elementary reading circuits (28) and an electrical output component (26) connected to the reading circuit. The detection array and the component are respectively fixed to two separate faces of the block.
