A novel modular design method for Moiré fringes detecting system using the embedded differential Mealy state machine was proposed in this paper. The were accomplished on the programmable device EP2C8Q208.The functionalities were simulated by using QuartsⅡ software. Experimental results show that the system has overcome the disadvantage caused by separate subdivision and recognizing circuits in conventional electronic subdivision method. And it has the following characteristics: high synchronization, high anti-interference ability, quick upgrade and debug. High precision displacement measurement is implemented.
