摘　　要：等离子体Hα径向分布的测量是等离子体实验中的重要内容。在HL-2A实验中,等离子体成像系统中的CCD图片记录了等离子体辐射信息,特别是Hα线辐射信息(在相机前加Hα滤光片)。因为光测量是辐射的线积分,数据的处理和分析显得十分必要的。利用等离子体可见光成像系统,采用Abel变换,得到Hα在HL-2A装置中的径向分布,提供了一项可靠的测量手段。Measurement of Hα radial distribution is an important part in a plasma experiment. During the HL-2A experiment, CCD photos recorded the plasma radiation information using a plasma imaging system, particularly the Hα line emission information （with Hα filter in front of the camera）. Since the line of light radiation measurement involves a line integral of the radiating region, data handling and analysis are necessary. The Hα radial distribution along an HL-2A tokarnak radial radius can be obtained by using an Abel inversion transformation with plasma imaging on the HL-2A tokamak. This paper provides a reliable measurement method on the HL-2A tokamak.
