TWIST ANGLE MEASURING SYSTEM Russian patent published in 2018 - IPC G01B11/26 

FIELD: measuring equipment.

SUBSTANCE: invention is intended to determine the angle of twisting of a controlled object relative to a certain base in various industries, in particular in telescoping and rocket construction. System for measuring the twist angle contains a control element installed on the control unit and a triple prism, a diaphragm illuminated through the condenser by a radiation source, a radiation receiver made in the form of a CCD array, and an information processing unit. In this case, the system is equipped with an additional triple prism mounted on the control unit, while the vertices of the triple prisms are arranged symmetrically with respect to the optical axis of the system, and an additional diaphragm installed on the base, where the diaphragms are arranged symmetrically with respect to the optical axis of the system, and the distances between the vertices of the triple prisms and the centers of the diaphragms are equal to each other, in addition, the lens projects the centers of the diaphragms to the vertices of the triple prisms with an increase of unity.

EFFECT: increased transmission ratio by means of the twist angle and increased accuracy of the entire system.
