PHASE DISCONTINUITY MEASURING TECHNIQUE Russian patent published in 1994 - IPC

Abstract RU 2011949 C1

FIELD: measurement technology. SUBSTANCE: discontinuity is sounded by main light beam from which transformed beam is shaped with other wavelength and reversed wavefront. Transformed beam is used for sounding discontinuity. At discontinuity beam pass ratio equal to that of respective wavelengths ion component is interferometrically recorded. At reverse ratio of numbers electronic component is recorded. EFFECT: improved accuracy and speed of measurement. 1 dwg
