Abstract :
A novel concept of using a fiber optic technology to create a 3-D seismometer/accelerometer was proposed. The initial planar prototype exhibits a good linearity in the static calibration and less noisy signal in low-frequency dynamic tests. In the near future, a 3-D prototype will be subjected to a large set of tests in an environmental chamber to find the sensors output correlation/immunity to different ambient conditions such as temperature and humidity.
