FIELD: measuring equipment.
SUBSTANCE: receiver is a thin film resistive microbolometer, with the known radiation absorption coefficient, made of half-metal and located on a thin membrane. The essence of the invention consists in the fact that the thin film resistive element with the known absorption coefficient and the temperature resistance coefficient is both a temperature-sensitive element and an absorber, that allows to calibrate independently the device with sinusoidal electric current to determine its Volt-Watt sensitivity.
EFFECT: proposed device allows to measure the measurement flow density in the wide wavelength range of the MM spectra area with a high sensitivity and the given speed without the use of the reference calibration means for radiation.
