METHOD OF DETERMINING SPATIAL ORIENTATION OF OBJECT USING OPTOELECTRONIC SYSTEM AND CORNER REFLECTOR Russian patent published in 2015 - IPC G01B11/03 

FIELD: physics, navigation.

SUBSTANCE: invention relates to remote determination of the spatial orientation of an object. In the method of determining the spatial orientation of an object using an optoelectronic system, a corner reflector is rigidly mounted on the object and its entrance plane is illuminated with a light beam along the sight line. The reflected light beam is projected by the lens of the optoelectronic system on the photosensitive layer of a matrix photodetector to form an image of the corner reflector, from which the spatial orientation of the object is determined in the form of angles of successively rotating the corner reflector about three mutually perpendicular axes. The entrance plane of the corner reflector is also illuminated with a light beam that has passed through a diaphragm which limits transmission of the entrance plane, wherein the periphery of said diaphragm does not merge into the diaphragm when turned by an angle of 180°. The reflected light beam is projected by the lens of the optoelectronic system on the photosensitive layer of a matrix photodetector completely, and the spatial orientation of the object is determined from the shape of the periphery of the image of the corner reflector.

EFFECT: broader functional capabilities of determining spatial orientation of objects in a wide range of distances.
