METHOD AND APPARATUS FOR MEASURING PROFILE OF SPHERICAL INCURVED, PARTICULARLY, CYLINDRICAL BODIES Russian patent published in 2014 - IPC G01B11/25 

FIELD: physics.

SUBSTANCE: invention relates to a method of measuring the profile of cylindrical bodies as measured objects using a two-dimensional slit method, wherein by using at least one laser, a fan-shaped laser line is projected as a slit line on the surface of a body and beams reflected from the surface of the body are picked up by at least one camera for photographing surfaces, wherein the laser and the camera are arranged at an angle of triangulation in the normal plane on the axial line of the cylinder. To measure the profile according to the method, the laser is rotated around the axis of the cylinder from the normal plane, wherein the angle to the normal plane is selected such that the optical axis of the camera for photographing surfaces, directed towards the surface of the cylinder, is in the region of sliding angles of reflected beams.

EFFECT: stronger reflection of laser beams towards the camera and from critical peripheral regions of the measured object.
