DEVICE FOR SPATIAL ORIENTATION OF OBJECTS Russian patent published in 2002 - IPC

FIELD: measurement technology; designing devices for determination of relative turn (twisting angle) of spaced-apart objects for transmission of vector in distance, for example, azimuth bearing, from plane of one level to plane of another level, etc. SUBSTANCE: device for spatial orientation of objects includes two opposite reflectors: one reflector made in form of at least one right-angle prism, objective located between reflectors, two marks with illuminators, system forming images of marks symmetrically relative to axis of objective from microobjectives located behind plane of image of objective with receiving prisms and receiving unit. Novelty of invention consists in that the first reflector in way of beam is made in form of triple prism mounted coaxially relative to objective; marks are rigidly interconnected; they are mounted in object plane and are directed towards triple prism; mark unit formed by marks with illuminators, microobjectives and receiving prisms is mounted for rotation around optical axis of objective. EFFECT: high accuracy at high degree of reliability of determination of spatial orientation of objects under varying operating conditions at distance unlimited. 4 cl, 1 dwg
