OPTICAL DEVICE Russian patent published in 2002 - IPC

FIELD: optical instrumentation. SUBSTANCE: optical device is designed for instruments used in external trajectory measurement in space geodesy and in proving ground measurement. It includes supporting-rotary unit on base, units and drives for rotation around azimuthal and angle-of-elevation axes with transmitters of angle of turn, opticoelectron equipment, opticomechanical unit with radiator and reflecting elements installed in sequence. Supporting-rotary unit includes fork with two posts and pin. Opticomechanical unit is located between base and frame. Hollow shaft is set in bearings, on posts of fork. One optical unit is joined to each end of shaft with use of flange. Reflecting elements form light guide with potential for passage of optical beam from one optical unit to opticomechanical unit. Hollow shaft has cut-out that houses one reflecting element. Pin is installed in two bearing supports spaced apart by height. Each drive includes snap-action motor comprising rotor and stator. One bearing support of each axis of rotation of supporting-rotary unit is fitted with aid compensating for temperature deformation. EFFECT: development of compact, multifunctional, portable, high-precision optical device for observation of flying objects. 4 cl, 2 dwg
