【Abstract】 From each buildups of the optical fiber displacement sensor,an complex method to improve the measurement range of the reflective fiber optic sensor for displacement. It is pointed out that the combination of controllable optical source method and gain-programmed amplifier method can break the restriction of measuring range of photoelectric detector and A/D analog-to-digital converter, solving the problem of low sensitivity and detecting dead area. Different combination can be used to spread measuring range according to different requirements .更多还原
