DEVICE FOR MEASURING ANGULAR POSITION OF REFLECTORS Russian patent published in 2008 - IPC G01B11/26 

FIELD: measuring technique.

SUBSTANCE: device comprises first autocollimator (1), first unit of collinear beam transfer (2) flat mirror reflectors (3)-(10), first and second pickups of rotation angle provided with rotors (11) and (12) and stators (13) and (14), first platform (15) provided with first autocollimator (1) first unit for collinear beam transfer, and stators (13) and (14) of the first and second pickups of rotation angle. First reflector (3) is rigidly connected with rotor (12) of the second pickup, second reflector (4) is secured to stator (13), and third reflector (5) is secured to rotor (11) of the first pickup, sixth reflector (8) is rigidly connected with second reflector (4), seventh reflector (9) is secured to third reflector (5), and eighth reflector (10) is rigidly connected with first reflector (3). First autocollimator (1), first unit for collinear beam transfer (2), and first (3), second (4), third (5), fourth (6), fifth (7), and sixth (8) reflectors are optically interconnected. The angle converter is provided with additional second autocollimator (16), second unit for collinear beam transfer, flat mirror reflectors (18)-(21), third rotation angle pickup having rotor (22) and stator (23), clutch (24), second platform (25) provided with second autocollimator (16), second unit for collinear beam transfer (17), stator (23) of the third pickup of rotation angle, and clutch (24). Second platform (24) is cinematically connected with first platform (15) and rotor of the first pickup is connected with second platform (25) through clutch (24). Reflector (18) is rigidly connected with rotor (22) of the third pickup, tenth reflector (19) is rigidly connected with stator (23) of the third pickup, eleventh reflector (20) is rigidly connected with reflector (9), and twelfth reflector (21) is rigidly connected with the ninth reflector (18). Second autocollimator (16), second unit for collinear beam transfer (17), seventh reflector (9), tenth reflector (18), tenth reflector (19), and eleventh reflector (20) are interconnected optically.

EFFECT: enhanced precision.
