METHOD OF CONTROLLING BULKINESS OF EQUIPMENT LAYOUT IN TUNNELS AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2012 - IPC G01C7/06 G01B11/24 

FIELD: physics.

SUBSTANCE: method involves illumination of the surface of a tunnel with a light beam, viewing outlines of the illuminated part of the tunnel, comparing the scanning contour with a reference contour and measuring deviation of the scanning contour from the reference contour. The apparatus has an illumination source, an optical system and a television radiation receiver. The illumination source used is a laser fitted with a scanning system with a mirror reflector. The optical system is configured to project the scanning contour onto the television radiation receiver.

EFFECT: enabling coordinate measurement and high reliability of control.
