FIELD: physics.
SUBSTANCE: method of scanning a luminance field with a photooptic system with a linear matrix receiver includes rotating the image of the luminance field, receiving and converting, using the linear matrix receiver, optical radiation into electrical signals and processing said signals. When the linear matrix receiver is rotated at a rate of ωLMR, the image of the luminance field is rotated around the sight axis of the photooptic system at a rate of ωS=ωI+ωLMR, where ωI is the rotational speed of the image of the luminance field for ωLMR=0. The photooptic system comprises series-connected lens, main mirror, prism, correcting lens, linear matrix receiver, signal processing unit with a linear matrix receiver, as well as a rotary drive for the housing of the prism, having series-connected phase detector, low-pass filter and dc motor, as well as a prism rotational angle sensor.
EFFECT: invention widens conditions of using a photooptic system with a linear matrix receiver by increasing sensitivity with or without rotation of the linear matrix receiver.
