摘　　要：在HL 2A装置上研制了等离子体可见光成像系统,用于孔栏、偏滤器位形放电的诊断。该成像系统由彩色摄像机、观察窗和转向镜、广角收集和准直透镜组、采集卡和计算机组成。本文描述了系统的布局和各部件参数的匹配,报道了观测到的实验结果。等离子体成像系统能监视放电的整个过程,实时显示可见光辐射图形,特别在识别孔栏与偏滤器位形放电的诊断中发挥了重要作用,成为HL 2A装置放电的重要诊断手段。A plasma visible light imaging system (PVLIS) has been developed for the diagnosis of plasmas with limiter and divertor configurations in the HL-2A tokamak. The imaging system consists of a color video camera, an observation window and a turning mirror, a wide-angle collector and collimating lens, a video capture card as well as a portable computer. The system layout and the parameter of each component are described. Experimental results obtained with the imaging system are briefly reported. Plasma discharge process can be monitored overall with the PVLIS and visible radiation pictures can be displayed in real time. The PVLIS will play an important role in plasma diagnosis,especially for limiter and divertor configuration dischanges,and should kecome a basic means of observation for the HL-2A discharges.
