| Abstract: | In this paper, the effect of the laser amplitude and phase noise affect on the s ystem of optical fiber strain sensor are discussed. The mathematical relation of the laser amplitude noise with resolution of fiber optical strain sensor is de rived. The methods for eliminating the effect of the laser amplitude and phase n oise and temperature noise from optical fiber sensor are presented. The results of experiment agree with the theory. |
