Abstract
A two-dimensional optical accelerometer, include a base, a two-dimensional optical angle measurement apparatus and a seismic apparatus. The two-dimensional optical angle measurement apparatus and the seismic apparatus are mounted on the base. In operation, the base of the two-dimensional optical accelerometer is attached to the vibrating structure. Vibrations of this structure cause angles of the seismic mass within the two-dimensional optical accelerometer. These angles are detected by the two-dimensional optical angle measurement apparatus, which generates a corresponding light intensity signal. The light intensity signal is acquired and used to calculate the acceleration acting on the base.
