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.
