The invention discloses a novel optical fiber deformation control device which comprises a base, optical fiber clamp holders and a piezoelectric ceramic tube. A 'V'-shaped groove is formed in the middle of the base, the upper portion of the groove is higher than platforms positioned on the left side and the right side of the groove, mounting holes are formed in the platforms, and a first optical fiber groove which extends along the left-right directions is formed in the surface of the groove; the optical fiber clamp holders are fixed to the left side and the right side of the base by the aid of the mounting holes in the base, and the piezoelectric ceramic tube is arranged in the groove along the extension directions of the groove; an optical fiber can be fixedly wound on the piezoelectric ceramic tube, and two ends of the optical fiber can be led out from the first optical fiber groove in the base and are ultimately fixed by the aid of the optical fiber clamp holders positioned on the left side and the right side of the base. The novel optical fiber deformation control device has the advantages that the piezoelectric ceramic tube can be controlled by a driving power source, the diameter of the piezoelectric ceramic tube can be changed, the optical fiber which is fixedly wound on the piezoelectric ceramic tube can be driven by the piezoelectric ceramic tube to deform, and accordingly deformation of the optical fiber can be precisely controlled.
Description
technical field [0001] The invention relates to a deformation control device, in particular to a novel optical fiber deformation control device. Background technique [0002] Tunable fiber lasers have been widely used in many fields such as communication, sensing, remote sensing, and detection. Among them, in the field of synthetic aperture lidar, a signal with a large time-width is obtained through a tunable fiber laser, and then a signal with a large bandwidth is obtained through back-end tuning, thus generating a signal with a large time-width-bandwidth product, making the synthetic aperture lidar high resolution detection is possible. [0003] In tunable fiber lasers, compared with Michelson interferometers, Mach-Zehnder interferometers greatly reduce echo interference because they have no mirrors, and are widely used in the tuning field of fiber lasers. [0004] The Mach-Zehnder interferometer uses the arm length difference of the two interference arms to form interfe...
