LUMINANCE FIELD SCANNING METHOD AND PHOTOOPTIC SYSTEM FOR REALISING SAID METHOD Russian patent published in 2014 - IPC G02B26/10 

FIELD: physics.

SUBSTANCE: luminance field scanning method includes receiving radiation of an object using a photooptic system with a two-dimensional matrix receiver, converting the radiation to electrical signals, storing signals from elements of the two-dimensional matrix receiver, reading said signals and processing. When receiving radiation of the object using a photooptic system while rotating the two-dimensional matrix receiver, the image of the luminance field is rotated at the frequency and in the direction of rotation of the two-dimensional matrix receiver. The luminance field scanning method is carried out using a photooptic system which comprises series-connected objective lens, which includes an entrance window, a main mirror and a correction lens mounted on the beam path, a two-dimensional matrix receiver mounted in the focal plane of the objective lens and a unit for processing signals from the two-dimensional matrix receiver. A prism with a rotary drive is mounted in the objective lens between the main mirror and the correction lens, wherein the output of the rotary drive is connected to the second input of the prism. A unit for shifting the signal to half the frequency of the two-dimensional matrix receiver is connected between an additional sensor for the rotational angle of the two-dimensional matrix receiver and the rotary drive.

EFFECT: providing conformity between arbitrary luminance field elements and a two-dimensional matrix receiver in an aircraft rotating during flight.
