Abstract：基于多项式校正方法，建立了针对图像坐标的公式模型，利用MATLAB中的曲面拟合工具（Surface Fitting Tool）得到了多项式参数，实现了对紫外探测器成像畸变的校正。本文介绍了楔条形阳极紫外探测器的畸变产生原因以及多项式校正的原理，设计了一个应用于LabVIEW的dll模块，通过小孔掩模板实验求得多项式并应用于分辨率板的成像，实现了对分辨率板成像的畸变校正。

Abstract： The technology of far ultraviolet photon-counting imaging detection is to record each single photon position and achieve the purpose of general imaging by detecting weak single photon information. The counting rate limits the information acquisition. On the basis of analyzing factors affecting the counting rate, the front-end analog circuit is needed for the amplification and shaping of the detector signals. Eventually, A225 chip was chosen as the pre-amplifier and shaping circuit was designed in the analog front-end circuit. Corresponding simulation and experimental results show that the circuit design is reasonable, and the counting rate can reach 200 kHz.
