光学干涉测量是一种著名的高精度测量技术,它是通过光波叠加产生的光学干涉来实现的。然而,在光纤干涉测量中,由于环境振动不可避免地引起光纤的波动,使得测量结果不稳定,限制了干涉仪的使用场合,使得光的相位容易受到干扰。本文介绍了一种用于隔振的光纤太赫兹波干涉仪。由于太赫兹波的波长较长,光纤涨落对相位噪声的影响得到了很大程度的抑制。为了验证光纤太赫兹波干涉仪的可行性,本文利用光纤太赫兹波干涉仪测量了光纤尾带热光移相器的光学相移。实验结果表明,与全光纤干涉仪相比,光纤太赫兹干涉仪能够精确测量光学相移,并提高了干涉的信噪比,获得了6db的增益。
Optic interferometry is a well-known measurement technique with high precision attained through the optical interference caused by the superposition of lightwaves. However, with fiber-optic interferometry, the phases of the lightwaves are susceptible to interference via the fiber fluctuation that is unavoidably induced by the environmental vibration, which makes the measurement result unstable and limits the usage scenarios of the interferometric installation. In this paper, a fiber-optic THz wave interferometer aiming for vibration isolation is presented. Due to the longer wavelength of the THz wave, the influence of optical fiber fluctuation on the phase noise is considerably suppressed. For verifying the feasibility of the fiber-optic THz wave interferometer, it is used here to measure the optical phase shift at a fiber-pigtailed thermo-optic phase shifter. The experimental results show that, compared with an all-fiber interferometer, the fiber-optic THz interferometer enables accurate measurement of an optical phase shift as well as an improved signal-to-noise ratio of interference with 6dB gain.
