摘要
<jats:p>In order to meet the displacement measurement’s need for high precision and large measuring range, a novel design of optical fiber displacement system is proposed. Optical fiber is applied to the displacement measurement field with its simple structure, light weight, cheap cost and high precision. A displacement measurement model based on transmissive optical fiber is established, and theoretical calculation and simulation are conducted to verify the accuracy of the model. Displacement measuring experiments are completed and the results show that the transmissive optical fiber displacement measurement system has high measuring accuracy with the relative error less than 0.2% over a large range.</jats:p>
