FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment, namely to the creation of sensitive elements of spectral sensors and converters of physical quantities. Elastic element of the Bragg strain converter, made of quartz or a single-crystal material, is cantilevered in a support part. By means of an elastic beam and a rigid beam, two regions are formed therein: an area with elastic deformation and a region without deformations, with the possibility of fixing of an optical fiber with a Bragg fiber grating on the beams. Bragg fiber grating is fixed with glue so that from one end it is fixed on the rigid beam, and on the other – on the elastic beam. Effect of an external force on the elastic beam, by means of a rigid beam, is transferred to a small portion of the optical fiber containing a Bragg fiber grating.
EFFECT: increase in the spectral sensitivity of the Bragg buck strain converter.
