FIBRE OPTIC TRANSDUCER OF ANGULAR DISPLACEMENT Russian patent published in 2011 - IPC G01B21/00 

FIELD: physics.

SUBSTANCE: fixed line of reflecting surface is located at distance L from optical axis of in-optic fibre. Optical axis of the later is located at distance D from that of out-optic fibre. Note that design parametres of both are interrelated by the following expression;

, where r_c, Θ_NA is core radius and optic fibre aperture angle, respectively, X₀ is distance at which reflecting surface is located to displace through angle α.

EFFECT: higher operating performances, simplifier production of fibre optic transducer.
