Abstract

Optical fibers can be used as promising sensors in smart structures due to their novel characteristics. This paper presents a wavelength division multiplexing (WDM) technique in order to improve the application capacity of single reflective grating based fiber optic sensors to monitor large industrial structures at multiple points. The models are appropriate for the general extrinsic fiber optic sensors such as the grating panel-based fiber optic sensor. The manufactured WDM fiber optic sensor system was examined in order to demonstrate the feasibility for two parameter detections at two points using mirror mounted grating based fiber optic sensor.
