MATRIX CONVERTER Russian patent published in 2022 - IPC G01J5/42 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and pertains to a matrix converter. The converter is based on a matrix structure of cells of optical-acoustic converters with a dynamic capacitor at the external output, constituting a densely packed system of expansion chambers filled with working gas. A thin emission-absorbing metal film is located inside each of said chambers. One end of the matrix structure is an entrance window and the second one is covered with a flexible conductive membrane layer forming a system of flexible conductive membranes sealing the expansion chambers. A transitional plate with fixed electrodes is located inside the common compensation chamber, forming a system of dynamic capacitors with a flexible conductive membrane layer. An edge through microperforation is made above each expansion chamber in the flexible conductive membrane layer, and the flexible conductive membrane layer is made of single-layer graphene.

EFFECT: increase in the sensitivity, structural simplification and provided possibility of analysing the spatial distribution of far-infrared and low-intensity terahertz emission on a real time scale.
