METHOD FOR ANGULAR REFLECTOR ANGULAR PARAMETERS MEASUREMENT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC G01B11/26 G01B5/24 

Abstract RU 2697436 C1

FIELD: measurement technology.

SUBSTANCE: method can be used to measure angular parameters of mirror and prismatic corner reflectors. In method, beam PLR, directed from autocollimator to selected inlet / outlet opening area AR, preliminary passing through window in flat mirror. At that, over the selected input / output window area AR orienting one of two open symmetrical zones of the opaque diaphragm, which completely opens the selected area on the input / output window AR for beam passage PLR from autocollimator. After reflection in AR beam PLR directed to flat mirror, reflected from it and returned along the same path back to autocollimator with lens and micrometre. Image coordinates of autocollimator autocollimating mark are measured by micrometre for each of six zones (i = 1, 2, …6) inlet / outlet opening AR twice. Difference in coordinates is used to determine angular deviations for each of six directions of reflected AR beams PLR relative to direction of incident on AR beam PLR. Angular errors of dihedral angles are calculated by formulas AR.

EFFECT: higher accuracy and reliability.
