Abstract

The design of a portable FBG Interrogation System is presented in this paper. By using volume holographic phase grating as the dispersion spectral element, the interrogator achieves 5 KHz scanning frequency with a readout wavelength resolution of 1 pm. The total power consumption is less than 25 W.
