Abstract

Here we propose a new kind of phase-shifting interferometer by using an SPPCM with BaTiO₃. The phase shifting is derived from the inherent frequency shift of the SPPCM. The interferometer has two characteristics: self-generating phase conjugate wave and phase shifting. The interferometer is demonstrated to have good performance on the resolution of measurement.
