摘要：
In this paper, we present a novel design of spectral detection circuit for demodulating fiber Bragg grating (FBG). New type field programmable gate array (FPGA) has been used to make the circuit more compact. We use NIOS-II operating system in FPGA to deal with the real-time data measurement, so needn't any extra micro-programmed control unit (MCU) and other processing electronic devices. The circuit system in this paper, including the charge coupled device (CCD) driver, signal processing, analog-digital conversion and processing of optoelectronic image data, can be widely used in FBG sensor field.
