As for our knowledge, a simplest real-time system for measuring dynamic optical phase perturbation is proposed and demonstrated. In this system a 1% weight Fe: LiNbO3 is used to record the self-interference grating by the incident light. The interferometer is a new kind of double-exposure one. The speed of the interferometer is as fast as that of the dynamic phase perturbations.
