METHOD FOR DETERMINING ANGULAR POSITIONS OF OBJECT SURFACE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G01B21/22 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement of a deviation angle of surface of controlled objects from a basic level, a profile and curvature of surfaces of parts in machine-building industry. A device implementing a method for determining angular positions of object surfaces includes a radiation source, a light-guide system consisting of two harnesses of light waveguides, a photoreceiver, two comparators with different comparison levels, a shaper of comparison levels, two units for detection of middles of electrical pulses, a recording unit of time intervals, an electric motor, an optic head piece and a light waveguide of the optic head piece. The latter is made in the form of a hollow cylinder, and the light waveguide of the optic head piece is installed diametrically in the side wall of the cylinder. Besides, the invention introduces a reference signal mark installed on the optic head piece, a pulse sensor of the reference signal, the output of which is connected to the input of the second comparator.

EFFECT: enlargement of the range of measured angular positions of controlled surfaces by increasing the time of simultaneous existence of sounding and received - reflected radiation flows.
