Abstract

With the development of the spectral survey project, the miniaturization, high density, integration and high precision positioning requirements of the fiber positioning unit have become a general trend, which also puts forward higher technical requirements and challenges for the optical fiber positioning system. At the same time, fiber positioning technology also expects to achieve high-precision real-time monitoring and feedback system to form an effective closedloop control. This propose a the concept design of the fiber positioning real-time monitoring system with four-quadrant detector based on the parallel controllable fiber positioning technology of LAMOST.
