TWO-CHANNEL MATRIX INFRARED RECEIVER OF FACETTED TYPE RADIATION Russian patent published in 2019 - IPC H01L31/42 

FIELD: optics.

SUBSTANCE: invention relates to optical instrument-making and relates to infrared radiation receiver. Two-spectral infrared radiation detector comprises a thin-film matrix structure of planar photovoltaic cells based on lead selenide, equipped with optical filters and arranged around common axis along circle with alternation of photovoltaic elements of two different channels of spectral sensitivity. Photovoltaic cells in an even number of at least 12, made on separate substrates in the form of rectangles and isosceles triangles, are assembled into a volume matrix structure arranged on a structural base, having the shape of a regular truncated pyramid. Photovoltaic cells made in form of rectangles are arranged on side edges of regular truncated pyramid, and photovoltaic elements made in the form of isosceles triangles are arranged on the upper base of the regular truncated pyramid.

EFFECT: technical result is increased field of view and application of radiation source selection both on spectral characteristics and spatial arrangement.
