In this paper,the two-value problem in fiber-optic displacement sensors based on the principle of collimated beam reflective intensity modulation is investigated. In order to solve this problem,a photosensitive component is set on its surface to indicate the range of its movement. For the purpose of eliminating such effects as fluctuations of the light source and the reflectivity difference of the reflective plane on the measuring results,a double lightpath structure is designed. Moreover,a C8051F410/2 microcontroller-based circuit of signal detection hardware is presented.
