METHOD OF CONTROLLING SHAPE OF INTERNAL PARTS Russian patent published in 2017 - IPC A61B1/15 G01B11/02 

FIELD: measuring equipment.

SUBSTANCE: method for controlling the shape of internal parts, including the steps of delivering inside the equipment to be controlled an endoscope with the miniature camera, made with the possibility of measurements, for navigating along the trajectory of which lighting with white light is used, which is transmitted over an optical fiber, after quitting which the required lightness indicatrix is formed with at least one lens. Thereinafter, the distal end of the endoscope is aligned orthogonally with the controlled surface by means of mechanical articulation. Then follows the step of switching off or muffling the white light, followed by turning on the laser, which, by means of the optical fiber transmitting the laser flux and the capacitor, generates a parallel beam of rays which, passing through a diffractive optical element, forms an image with known dimensions on the surface of the controlled object, and then, using the resulting digital image of the part and the laser image projected thereon, calibrating is carried out, followed by comparing the images, and in case of detecting the discontinuities, measuring the geometrical parameters of the part is carried out.

EFFECT: improving the efficiency and productivity of controlling the shape of internal parts.
