一种光泵磁力仪自动捕获跟踪系统的设计
Design of automatic catching and tracking system in optical pumping magnetometer
摘要
Abstract
The discrete modified VCO was adopted to design an automatic catching and tracking loop in optical pumping magnetometer, and its auxiliary catching function was achieved with the subsequent central controller. The experiment indicates that the loop can realize the tracking accuracy of 1 Hz, and the renewed catching time is less than 5 s. Compared to the manual adjustment or special auxiliary catching circuits, this tracking system takes advantage of the redundant resources of the subsequent central controller, and reduces complexity and size of the equipment. Furthermore, the VCO modules arc built with cheap discrete components, so that the cost is reduced further more. All of the above shows the favourable applied prospects.关键词
