Abstract:
    This invention disclosed a FBG sensor and wavelength scaling device working in low temperature liquid helium circumstance. It consists of screw micrometer head and a cantilever dynamic platform. The characters are as follows: place the micrometer head and platform into a low temperature Dewar flask with liquid helium; a cantilever was fixed on the platform; the micrometer head was fixed on cover of the Dewar flask; one end of the head was connected to the displacement pole in the flask to form a force application device; the grating sensor of the FBG was sticked to the cantilever arm. The base and backbone of the cantilever arm were made of epoxy stuff.
