An accelerometer based on an in-fiber Bragg grating sensor has been fabricated and demonstrated. The grating sensor operates linearly up to accelerations of 170,000gn. The design, testing and performance of the accelerometer are discussed.

Key words : fiber Bragg gratings, fiber optic sensors, accelerometer, photosensitivity
