Radiometric method of residual measurements of temperature of remote objects in infrared range of wavelengths is based on optical amplification of power of infrared radiation x from heated object K transformation to power of powers of fluxes of infrared radiation, measurement and remembering effective values of powers with following determination of effective temperature value Taccording to equation of measurement. First one forms first flux x= Kxof infra-red radiation with power proportional to normalized by value temperature Tto fourth power, with transformation of power of first formed flux to power U, with measurement and storing effective value of voltage. One transforms to power Upower of optically amplified K times flux x of infrared radiation from heated body, thus flux x= Kkx, where k– coefficient of decay of power of flux of infrared radiation having come from heated object through atmosphere to radiometer, one measures and stores effective value of voltage obtained. One artificially forms the second flux x= K (x+kx) of infrared radiation through combining fluxes of infrared radiation with known and unknown values of powers. One transforms power of second formed flux xto voltage U, with measurement and storage of effective value of that voltage, and on real value of temperature one makes conclusion according to equation of excess measurements, i.e |
