Abstract
An optical frequency domain technique is applied in this paper. The sampling method generally used is analyzed here. Calculations consequence shows that sampling signal from branch composed with double reflectors seems not so excellent in simulation, signal periods of this arm due to different distance of reflectors are compared, and consequence shows coincidence with principle and simulation. It means proportional relationship of frequency and distance of double reflectors. Strain is added to FBG sensor and measured at a point of optical fiber arm, with its location tested also.
