Abstract
Recent progress on the development of flexural disk based fiber optic acceleration sensors is reported. Appropriate geometric considerations have resulted in fiber optic accelerometers with many desirable features including (i) high sensitivity (≳20 dB re rad/g), (ii) flat frequency response (200 Hz to ≳10 kHz), and (iii) low pressure (<−180 dB re rad/μPa) and transverse sensitivity (<−30 dB). Alternate transducer designs are discussed and preliminary results reported. Various optical multiplexing schemes for accelerometer arrays are discussed.
