METHOD FOR SPECTRAL DEFORMATION TRANSDUCER SENSITIVE ELEMENT PRODUCTION Russian patent published in 2017 - IPC G01L1/24 

FIELD: physics, instrumentation.

SUBSTANCE: invention refers to the field of optical instrumentation and can be used for creation of the primary sensitive elements of fiber optic deformation sensors and transducers of spectral type. The inventive method for manufacture of the spectral deformation trasducer sensitive element includes placement of optical fiber with a fiber Bragg grating on the elastic member surface, a layer of elastic adhesive material is applied on the fiber Bragg grating, so that the optical fiber portion over the entire length of fiber Bragg grating is fixed on the elastic member surface. At that, the assembly is kept until complete solidification of the elastic adhesive material, and a layer of non-elastic adhesive material is applied to the edges of the solidified elastic adhesive material, so that the optical fiber beyond the length of the fiber Bragg grating is rigidly attached to the elastic member surface, the assembly is kept until complete solidification of the non-elastic adhesive material.

EFFECT: invention provides improved accuracy of spectral deformation transduction.
