GEAR MEASURING RELATIVE ANGULAR POSITION OF REFLECTORS Russian patent published in 2002 - IPC

FIELD: measurement technology, measurement of relative angular positions of mirror reflectors, high-precision transmission of angular coordinates. SUBSTANCE: gear has autocollimator, unit of collinear transfer of beams and six flat mirror reflectors. It is supplemented with seventh and eighth flat mirror reflectors, first and second angle data transmitters, each comprising rotor and stator parts, and platform that carries autocollimator, unit of collinear transfer of beams. Stator parts of first and second angle data transmitters. In this case starter part of first angle data transmitter is made fast to second reflector and axis of rotation of rotor is parallel to this reflector. Stator part of second transmitter is made fast to fifth reflector and its axis of rotation is parallel to this reflector. Seventh flat mirror reflector is made fast to rotor of first angle data transmitter and is oriented in parallel to axis of rotation of rotor. Eighth flat mirror reflector is made fast to first reflector and is oriented at right angle to it. First reflector is made fast to rotor of second angle data transmitter. EFFECT: increased measurement precision, potential for formation of system of high-precision spatial transmission. 1 cl, 1 dwg
