DEVICE FOR CONTROLLING INTERNAL SURFACES OF BODIES Russian patent published in 2006 - IPC G01B11/30 G02B23/24 

FIELD: automatics, engineering of controlling devices.

SUBSTANCE: device has cylinder-shaped body with serially positioned lighting system, consisting of electronic lamp and toroidal lens, surveillance system, consisting of conic mirror for all-around observation, objective, light guide, scale mesh and ocular. Additionally inserted are second objective, positioned in front of input end of light guide and forming its image in plane of scale mesh, positioned in focal plane of ocular, optical axis of which coincides with axis of second objective micro-objective, positioned on optical axis, parallel to ocular axis and axis of second object respectively. Second objective and micro-objective are mounted with possible mutual displacement for serial mounting on optical axis of ocular, micro-objective is focused on output end of light guide and builds image of fragments of light section in plane of scale mesh, second objective, scale mesh, ocular and micro-objective are constructively combined in single block, mounted at output portion of light guide with possible movement in two orthogonal directions.

EFFECT: improved sensitivity of device, improved precision of defects dimensions estimation.
