Abstract

A miniature fiber-optic accelerometer was constructed and tested. Optical phase modulation was employed. A multimode diode laser served as the optical source for the single-mode optical fiber. The resulting sensor element is 2.5 cm long and 0.25 mm in diameter. The acceleration range measured extended from below 104g to above 3g. The upper limit was due to limitations in the test equipment rather that the accelerometer. The device was designed to operate to above 10g. The frequency range investigated was 100 Hz to 25 kHz. Here again the upper frequency was limited by the test equipment. An undesirable cross-axis resonance was observed at 2.8 kHz. Techniques for moving this resonance to above the operating range are described.
