METHOD OF DIAGNOSING DAMAGES IN TESTED OBJECT Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: device can be used for diagnosing damages by means of thin-filmed threshold-type detectors. Site is found and fact of mechanical damage is established by means of measuring device generating measuring signal, which is sent registration system. Optical fiber is used as sensitive element. The fiber is bent to have specified radius of curvature in form of random line or zigzag-type line either grid along total surface of first dielectric base with preset pitch. Fiber is rigidly fixed between first and second dielectric bases made of optically transparent and elastic material. Bases are connected together by means of thermal-compression bonding. Fiber is connected to light source and to registration system interrogation control desk photoreceiver through shockproof optical connector. Optical detector is mounted onto surface of inspected object and modeling of process of damage of tested object is performed under effect of bullet or fragments of bursting ballistic element. Fact is established and sort of damage is identified due to processing of received data in electro-optical converter of registration system interrogation desk.

EFFECT: improved reliability of registration; reduced power cost.
