RUNNING SURFACE WRAP AND INHOMOGENEITY DETECTOR Russian patent published in 2009 - IPC G01B11/30 

FIELD: physics.

SUBSTANCE: running surface wrap and inhomogeneity detector includes sensor designed as fibre-optic measuring probe with radiating and receiving light guides and electronic module. Fibre-optic measuring probe represents two beams of radiating and receiving light guides by randomised optical scheme covered with the third beam of receiving light guides thus ensuring coaxial optical scheme, with working beam ends lying in one plane. Working beam ends are movable and fixed relative to the controlled surface. Additionally receiving light guides of beams are connected through optoelectronic converters to the adder with output connected to the indicator, while radiating light guides of beam are connected to pulse generator.

EFFECT: higher detection accuracy of various wraps and inhomogeneities of controlled surface.
