Temperature resolution of computer-integrated polarization thermal imager
Keywords:
polarization thermal imager, energy resolution, noise equivalent temperature difference, degree of polarizationAbstract
The work is devoted to the development of a method for determining the energy (temperature) resolution of a polarization thermal imager, which contains a linear polarizer and a phase plate. For this purpose it is proposed to use the noise equivalent temperature difference (NETD). A physico-mathematical model of an optoelectronic system of the polarization thermal imager has been developed, which allows one to calculate its signal transmission function. Based on this function, a method for calculating NETD has been developed. The formula describing functional dependence of a polarization thermal imager temperature resolution on the angular orientation of the polarizer relative to the optical axis of the phase plate at a given degree of polarization is obtained. A study of the impact of a test object radiation degree of polarization on the polarization thermal imager temperature resolution was performed. Bibl. 8, Fig. 7, Tabl. 1.
