METHOD FOR PHOTOMETRIC DIAGNOSTICS OF MATERIAL STRUCTURAL CONDITION BY DATA OF THEIR SURFACE DIGITAL CODED IMAGE ANALYSIS Russian patent published in 2010 - IPC G01N21/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to methods of nondestructive check and diagnostics of technical condition of objects from condensed material by data of structural image photometric analysis (SIPA) for their surface fixed in digital code and analysed on personal computer. Method consists in the fact that digital coded images of material surface fragments are fixed before and after material exposure, which resulted in its local damage, and a spectrum of reflection brightness is produced for each image. Extent of material degradation at this fragment is identified as ratio of this fragment image spectral brightness density variation to its maximum variation to picture fragment with limit degradation that complies with condition of damage, and extent of degradation is used to identify value of parametre that characterises operational suitability of material.

EFFECT: invention provides for the possibility of quantitative assessment of structural condition and extent of operational suitability of materials.
