DEVICE FOR DETERMINATION OF ORIENTATION OF SIGHT AXIS Russian patent published in 2004 - IPC

FIELD: optoelectronic instrument engineering, applicable in development of optoelectronic systems for determination of turns of the operator's crash helmet in various branches of engineering. SUBSTANCE: the device has a sight, unit for measurement of the turn parameters, readout initiation set unit, correction unit, non-linear transformation unit, multiplication unit, the first and second adders, division unit, integrators unit. The sight and the unit for measurement of the turn parameters are located on the operator's crash helmet. The sight represents an optical collimator driver and has an inclined semitransparent plate, entry lens located on the zero sighting line of the operator's eyes. A mark-graticule is located in the lens focal surface. It is illuminated by a radiation source. The sight provides for display of the image of the mark-graticule in the operator's field of vision. EFFECT: expanded field of application and enhanced accuracy of determination of the sighting angles due to simultaneous sighting as a result of the turn of the movable base and direct measurement of turns relative to the three mutually perpendicular axes of the given base with a subsequent formation of the angles of vertical and azimuth sighting in the base coordinate system. 13 dwg
