METHOD OF MAKING SENSITIVE ELEMENT OF SPECTRAL DEFORMATION CONVERTER Russian patent published in 2016 - IPC G01B11/16 G01D5/353 

FIELD: instrument making.

SUBSTANCE: invention relates to precision instrumentation and can be used in designing primary detecting elements of optical converters deformations spectral type. Disclosed method of making sensitive element of spectral converter of deformation on surface of elastic element is placed a non-photosensitive optical fibre and a layer of optically transparent non-photosensitive glass-ceramic material, assembly of elastic element, optical fibre and glass-ceramic material is placed in furnace, where metal-glass joint is soldered. Method then includes removing from furnace and cooling down at a rate of 5-8 °C/min in structure of non-photosensitive optical fibre coated with layer of hardened optically-transparent non-photosensitive glass ceramic material. In zone of maximum deformation of elastic element a Bragg grating is formed, and materials of structural components of sensitive element of spectral converter of deformation is selected with close values of thermal expansion factor.

EFFECT: technical result is simplification of technology of making sensitive element of spectral converter of deformation and high accuracy of spectral conversion.
