Keyword偏振观测 定标单元 控制方案 远程控制

云南天文台的一米新真空太阳望远镜(New Vacuum Solar Telescope,NVST)是我国在太阳物理和空间科学学科上对太阳进行光学和近红外观测的主力设备,其主要科学目标之一是高精度、高时空分辨率的太阳磁场测量。NVST采用机械扫描偏振观测方式,由于其光学系统的结构特性导致望远镜在跟踪太阳的过程中不可避免的引入了随时间变化的偏正效应,因此在进行偏正观测时需要进行系统定标,整个系统由定标单元、分析单元和探测器组成,其间涉及的多个运动部件均有复杂精密的运动要求。针对偏振定标过程和偏振观测过程中各光学件的运动需求,文章给出了定标单元和分析单元的控制要求,实现了不同观测模式时各部件的运动要求。基于TCP/IP协议的远程控制方案,集成了采用串口通讯的各商品驱动控制器,开发了一套在.NET架构下的定标单元控制软件和相应的用户界面,并预留了OCS接口。性能测试表明,系统符合实际观测要求,现已投入使用,为后续的偏振观测奠定了基础。 

Other Abstract

The new Vacuum Solar Telescope (NVST) is one of the most important solar observing systems, one of its main scientific goal includes high precision and high temporal resolution measurement of the solar magnetic field. NVST polarization analysis system should be pre-calibrated before observing, and, due to the structural characteristics of its optical system, NVST inevitably introduces a time-varying biasing effect during the tracking of the sun. Therefore, calibration of the system requires calibration of the system. The whole The system consists of a calibration unit, an analysis unit and a detector. A plurality of moving parts involved in the process have complex and precise movement requirements. This paper is aimed at the motion requirements of each optical component during polarization calibration process and polarization observation, gave the control requirements of the calibration unit and the analysis unit, and realized the movement requirements of the components in different observation modes. Based on TCP/IP protocol remote control program, integrated with serial communication of the commodity drive controller, the software is developed under the .NET architecture and set aside the OCS interface. System performance tests show that, in line with the measured application requirements, is now put into use, for the subsequent polarization observation laid the foundation.
