| Abstract: | An optical fiber accelerometer was designed based on a fiber-mirror interference cavity.The sensing principle and elastic structure of the accelerometer were introduced and its performance was measured.A silicon micro-mirror mounted on a mesh spring elastic structure and a fiber facet were used to form a fiber-mirror cavity to generate optical interference signals as a function of acceleration.A Phase Generated Carrier(PGC) technology was adopted to modulate the interference signals to obtain phase differen... |
