METHOD OF DETERMINING ANGULAR COORDINATE OF PULSED POINT RADIATION SOURCE Russian patent published in 1994 - IPC

FIELD: optical detection and ranging. SUBSTANCE: line image 1 is formed. Then image is transformed by means of 2n-channel parallel integral conversion into photo current of illuminance distribution in the direction being perpendicular to axis of line when photosensitivity is distributed in each pair of channels of channel photosensitive region 4 of single digit corresponding to direct and inverse values 2 and 3 of n-digit Grey-code. Interchannel signal differences are formed. Coordinate X_o of line is determined by summing two components X₁ and X₂. EFFECT: improved precision of determination. 2 cl, 5 dwg
