Based on the characteristic formula expression of the intensity modulation of planar single fiber pair, a mathematic model of single fiber fair intensity modulation is established. After simulation experiment, the influence of fiber spacing, fiber core diameter and fiber numerical aperture on the modulation characteristics of the sensor is summarized.展开更多

文摘This paper introduces the application of a slant lens fiber in a reflective fiber optical displacement sensor, namely the receiving fiber use the slant lens fiber. Based on the characteristic formula expression of the intensity modulation of planar single fiber pair, a mathematic model of single fiber fair intensity modulation is established. After simulation experiment, the influence of fiber spacing, fiber core diameter and fiber numerical aperture on the modulation characteristics of the sensor is summarized.
