Abstract
A highly sensitive device for measuring the parameters of transverse energy distribution in a beam of infrared radiation is described as part of an automated system of synthesis of dynamic and static infrared images. The system is designed to monitor the characteristics of matrix photo-receivers in the spectrum of 2,5–4,6 μm at irradiation levels in the range of 10 –9–10 –5 W/сm2. The device is subject to periodic gradation and verification of the accuracy of movements of the Foucault knife line movements at two coordinates. Measurements with the use of the device are carried out in accordance with state and industry standards of the Russian Federation. The scan error for each coordinate does not exceed 1 micrometer. The device measures the function of energy concentration, the concentration of energy in the plane formed image in the working spectral and dynamic ranges of the system.
