I propose and demonstrate a highly-sensitive motion detection based on fiber Fabry-Perot interferometry with resolution below 100 nm. The interferometer is based on a fiber-optic collimator, specially designed for efficient signal back-coupling, and a discrete moving reflective mirror forming the Fabry-Perot cavity. To enhance the sensing range, I propose a dual-cavity fiber Fabry-Perot interferometer, the main idea based on the interference pattern of the two signals. Experimental results then showed that the proposed sensor is capable of sensing in a displacement range up to 1500 um with resolution of 2 nm and stability within a wide area of 2 mm. Furthermore, I evaluated the influence of the angular offset on FFPI performance.
