FIELD: physics.
SUBSTANCE: matrix system of bolometre-type video converter comprises: (a) a matrix of i×j bolometre-type pixel detectors for tracking radiation from an object; (b) a housing in which said matrix of detectors is placed, where said housing has a front window which exposes detecting elements of all i×j pixel detectors of radiation coming from an object; (c) at least one closed bolometre-type detector in a housing in the column j+1, where detecting elements of said at least one detector are exposed by one or more standard surfaces; (d) a circuit for reading radiation readings from an object tracked by each of the i×j detectors of the matrix, and for reading radiation readings of the housing tracked by said at least one closed detector; and (e) a compensation circuit.
EFFECT: design of apparatus for direct measurement of different levels of infrared radiation of a housing on each pixel detector of a video converter matrix.
