由于色散干涉仪不受机械振动的影响，因此即使对于具有短波长的探测光束也不需要振动补偿系统。本文介绍了一种新的色散干涉仪的信号处理方法，即利用光弹调制器的调制幅度比。所提出的方法是免疫检测信号强度的变化，从而使信号处理系统简单。文中还给出了色散干涉仪的光学系统设计，特别是非线性光学晶体的规格。
Since a dispersion interferometer is free from mechanical vibrations, it does not need a vibration compensation system even for a probe beam with a short wavelength. This paper describes a new signal processing of the dispersion interferometer using a ratio of modulation amplitudes with a photoelastic modulator. The proposed method is immune to changes in detected signal intensities, thus making the signal processing system simple. Designs of the optical system of the dispersion interferometer for proof of principle, especially specification of a nonlinear optical crystal, are also shown.
