空间热离子成像探测器

研制一种用于热离子、紫外、X射线等多种目标源的成像探测器.该探测器输出为一张目标源的灰度图像，该图像的灰度等级及其分布对应目标源的强度分布，图像的灰度分布均匀性对应目标源的束流均匀性.以紫外光源作为目标源对探测器的性能参量进行实验测试，实验结果表明该探测器的空间分辨率优于120 μm，输出均匀性优于97%，输入输出正比性误差小于±4%.

Abstract

A kind of space thermal-ion imaging detector was investigated, which can be used in detecting a variety oftargetsource such as thermion, ultraviolet, X-rays etc. The output of the detector is a grayscale image of the target source, the detail information including the gradation level and gradation distribution of the image are obtained based on the intensity and thermal-ion uniformity of the target source. This paper conducted experiments to test the detector with target source of ultraviolet light.Performance parameters as follows have been detected; the resolution is better than 120 μm; the input-output linearity error is <±4% and the output uniformity is better than 97%.
