The work of this paper is to fabricate optical fiber displacement sensors. This system consists of four optical fibers of different sizes as the transmitting and receiving optical fibers, and the number of hole diameters of the four optical fibers are measured through displacement. Meanwhile, based on the design concept of low-cost optical fiber sensors, LED is used as the light source to record the changes of the light spot and conduct data processing in Matlab software.
