Study on miniature fiber optic accelerometer system
摘要
Abstract
Fiber - optic accelerometer which is regarded as a kind of new fiber sensors plays an irreplaceable role in the field of precision measurement. Realization of fiber-optic signal demodulation is benefit for improving the accuracy of the sensor measurement and accelerating its utilization. Light FM phase generated carrier (PGC) is usually exploited for the demodulation of interferometric fiber-optic sensors signals. In order to achieve miniaturization of the fiber optic sensing system, improve the speed of data processing and demodulation accuracy, the design of fiber optic accelerometer digital system was proposed. By the demodulation hardware DSP and FPGA, the system detects the mini-disc fiber-optic Michelson interferometer phase signal. The experimental results showed that the mini-disc fiber acceleration measurement system had high sensitivity for small vibration signal detection, it was the highlight in the field of precision measurement.关键词
