ODOMETER FOR INTRATUBE GEAR-FLAW DETECTOR Russian patent published in 2006 - IPC G01C3/08 G01N21/954 G01S17/66 

FIELD: measurement engineering.

SUBSTANCE: odometer for intratube gear-flaw detector, which odometer is fastened to air-tight container of flaw detector, has electronic unit, light source, optical fiber provided with image forming system. Electronic unit, light source in form of IR radiation range LED and image forming system in form of fiber-optic bundle, couplers and CCD array are built hermetically inside resilient polyurethane base fastened from outside to air-tight container. Electronic unit has also CCD array controller to process information based on algorithms of calculation of distance. IR radiation range LED is connected with control output of controller through switch-transistor. Control input and video output of CCD array are connected with controller by means of serial terminal.

EFFECT: improved precision of measurement.
