【摘要】：研究了磁流体传感器在无磁场和有磁场情况下光透射特性的变化情况。施加磁场后,透射光功率与入射光功率之间呈非线性关系,且在不同磁场强度下透射光功率随入射光功率增大的过程中均在某一区间突然大幅增大。突然增大的区间具有最高的灵敏度,区间范围与磁流体传感器的薄膜厚度及入射光功率有关。
[Abstract]:The change of optical transmission characteristics of magnetofluid sensors without and with magnetic field is studied. The nonlinear relationship between the transmitted light power and the incident light power is observed after the magnetic field is applied. In the process of increasing the power of the incident light, the transmitted light power increases sharply in a certain region under different magnetic field intensities, and the region suddenly increases has the highest sensitivity. The range is related to the thickness of the film and the power of the incident light.
