ANGLE MEASUREMENT DEVICE Russian patent published in 2014 - IPC G01C21/24 

FIELD: measurement equipment.

SUBSTANCE: angle measurement device comprises a lens, a matrix radiation receiver, a calculation unit and a channel of geometric reference, comprising the following components optically coupled with the lens of the lighting unit, having three sources of light arranged at the angle of 120° to each other, a collimator unit including three input and three output point diaphragms, and a mirror-prism unit, forming a monoblock with diaphragms applied on it and rigidly connected to the reference plane of the angle measurement device. The mirror-prism monoblock is made of six side mirror faces and parallel refracting bases that limit them, the larger hexagonal of which with applied outlet point diaphragms faces the lens, besides, its adjacent ribs are arranged at the angle 120° to each other. The monoblock is made with three additional refracting faces, placed between large bases and appropriate side mirror face, making a sharp angle with the large base and placed in front of the output point diaphragm, each additional face is equipped with an input point diaphragm, and angles between the large base and three additional refracting faces and three side mirror faces, arranged in front of three input point diaphragms, are equal to 90°.

EFFECT: increased accuracy of a device without complication of its design and increase of weight and dimension characteristics.
