Abstract

A data acquisition system, which interfaces to an interferometric fiber optic pressure sensor, is presented. This system transmits a modulated signal to the sensing interferometer, demodulates the returning interferometric signal by way of digital signal processing, while simultaneously relaying control and signal data via PC based software.

干涉式光纤传感器的数字信号处理
介绍了一种与干涉式光纤压力传感器相连接的数据采集系统。该系统将调制后的信号传输到传感干涉仪,对返回的干涉信号进行数字信号处理解调,同时通过基于PC机的软件实现控制和信号数据的中继。
