AUTOCOLLIMATOR FOR MEASURING ANGLE OF TORQUE Russian patent published in 2010 - IPC G01B11/26 G02B27/30 

FIELD: measurement equipment.

SUBSTANCE: invention refers to measurement equipment, to measuring devices characterised with optic measuring devices, and can be used to solve a wide range of engineering problems including measurement of flat angles, such as adjustment of optic-electronic system, assembly large-sized constructions, remote control and remote transfer of values of the angle, etc. Autocollimator meant for measuring the angle of torque includes lighter, the following which is installed in beam direction: capacitor, mark, beam divider, objective, reflector in the form of triple prism, which is installed with possibility of being turned about optic axis, and one of the edges of the above prism has deflection from straight angle, photodetector array connected to the computing device. At that, mark is installed in focal plane of the objective, and photoreceiver - at autocollimating point. Photoreceiver is made in the form of two matrixes installed at autocollimating points, some part of the mark field is made in the form of linear raster, and some part - in the form of a line, and before some matrixes recording the mark field picture in the form of raster. In addition, linear rasters are tightly attached to them; at that, mark raster and additional rasters are oriented parallel to columns of matrix photoreceiver.

EFFECT: increasing measuring sensitivity, increasing the operating measurement distance and decreasing overall dimensions.
