| Research Abstract |
The objective of this study is to develop a compact FBG ultrasonic sensing system. A fiber ring laser with an FBG sensor acting as a resonant mirror was constructed. This system was capable of detecting ultrasound by using the wavelength dependence of the optical gain in the optical amplifier incorporated in the sensing system. Compared with systems proposed previously, the developed system can be constructed at around 10% in size, weight and cost.
