OPTICAL SOLAR SENSOR Russian patent published in 2014 - IPC G01C21/24 G01J1/20 B64G1/36 

FIELD: physics.

SUBSTANCE: sensor includes a wide-field input optical element, a coding mask, a light filter, a protective shield and a matrix photodetector. The input optical element is in form of a composite monoblock and has the shape of a quadrangular prism. The monoblock comprises a central prism in form of a quadrangular truncated regular pyramid, lateral faces of which have an absorbent coating and four identical lateral prisms in form of quadrangular irregular pyramids. One of the faces of each lateral prism has a mirror coating and that face is connected to the corresponding absorbent face of the central prism. The composite monoblock rests on the surface of the coding mask in which there is a central identification marker which is aligned with the axis of symmetry of the central prism and four identification markers which are symmetrically arranged around the central marker.

EFFECT: high accuracy of determining coordinates and providing uniformity of distribution of resolution of the sensor on the entire field of view.
