Paper Abstract

This paper presents an interrogation system based on the linear nGaAs photodiode array and volume phase grating. By applying SDM and WDM technology, we have developed the interrogation system based on the linear lnGaAs photodiode array and volume phase grating. The system has the following advantages: small size, low power consumption, high resolution, interrogation speed, repeatability and reliability. Experimental results show that the interrogation system can be used to interrogate the FBG sensors with wavelength bandwidth of 42nm, SNR of about 30dB, wavelength accuracy of ±15pm, and it shows a good prospect.
