Abstract

This paper presents a FBG sensor interrogation system utilizing VCSEL laser as the light source. Using saw tooth signal to drive the VCSEL input current, a continuous spectrum tuning range of 2nm can be obtained. Relationship between wavelength tuning range and scanning speed of the VCSEL is studied. TDM method is applied to increase the number of sensors in the system.
