Laser interferometer carrier modulator

The invention discloses a laser interferometer carrier modulator, mainly comprising multiple sets of primitives that at least take a primitive A and a primitive B as a unit. The primitive A is mainlycomposed of a circular tube, an optical fiber winding layer, a protective rubber layer, a circular tube inner wall electrode layer wire A, a circular tube outer wall electrode layer wire A, an opticalfiber winding layer optical fiber end A and an optical fiber winding layer optical fiber end B, and the primitive B is mainly composed of a circular tube, an optical fiber winding layer, a protectiverubber layer, a tube inner wall electrode layer wire B, a circular tube outer wall electrode layer wire B, an optical fiber winding layer optical fiber end C and an optical fiber winding layer optical fiber end D. According to the scheme of the invention, the large-range and wide-band carrier modulation of laser signals can be provided for a laser interferometer, when the arm length difference ofthe laser interferometer ba
