Paper Abstract

In this paper, a novel fiber bundle probe which can transfer energy and provide a real-time feedback signal of fiber positions simultaneously is proposed and demonstrated experimentally to improve the fiber positioning accuracy of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). The fiber bundle probe is composed of four asteroid cores around a transmitting energy core at the center of the fiber bundle probe. The excitation characteristics were investigated numerically when a light spot illuminates on the end of the five-core fiber bundle probe. The calculated result shows that the fiber bundle probe can provide a real-time feedback signal when the offset between the center of end of probe and the light spot is in the range of -349.5 ~ -99.5 μm and 99.5 ~ 349.5 μm. Then the fiber bundle probe is fabricated by stacking-capillary method.
