Abstract
In this paper, the influence of the Q point on the DEFPI fiber-optic sensors is comprehensively analyses. For a DEFPI fiber-optic sensor, the output signals vary with the different position of the operational point regarding to the same applied pressure. The optimal operational point is in the middle position of the fringe linear scope. In addition, we present a novel structure sensor to guarantee the stableness of the Q point.
