FIELD: physics.
SUBSTANCE: device has a resistive imaging bolometer sensitive to the electromagnetic radiation to be detected and designed to be electrically connected to a signal generating circuit, and a resistive in-phase signal attenuating bolometer which is electrically connected to the imaging bolometer such that current flowing through the in-phase signal attenuating bolometer is subtracted from current flowing through the imaging bolometer, where it has a means of controlling resistance of the in-phase signal attenuating bolometer by injecting current into it.
EFFECT: high accuracy of detecting electromagnetic radiation.
