Paper Abstract

The developed method and device of detecting of local and integrated deformation of the case allow distance in a wide range of change of pressure and frequencies to calculate parameters of the SDS, indirectly to analyze and to determine functions of transformation of mechanical and thermal not regulated influences while in service, including not regular situations. The method and device are based on: 1) sounding by test optical radiation of optical windows created in a design of potential danger objects, which functions in conditions of action accompanying and ineradicable DHF; 2) receptin opposites in phase opposition of the modulated optical beams; 3) differential measurement mechancial deformation, extending in the case PDO; 4) measurement of residual deformation in units of a measuring grid. For a range of measurements of deformation from 0 up to 108 Pa and up to 107 Hz at temperature of object up to 500 To is developed and tested a breadboard model of the device. In comparison with known methods the considered method of detecting has the increased sensitivity and extended range of measurement in support with high hinderancedefence from action of the accompanying parasitic factors of a various physical anuter, high efficiency and relative simplicity of realization.
