摘要

带有交叉延迟线（XDL）的微通道板（MCPs）光子计数探测器有望实现高质量和宽视场目标成像。然而，随着有效探测面积的增大，系统响应的均匀性将面临巨大挑战。在本文中，我们开发了一种宽视场为 120 毫米 × 50 毫米的 XDL 光子计数探测器。此外，我们还研究了图像失真的原因，并提出了一种部分多项式修正方法来缓解图像失真。实验结果表明，在所提出的方法下，漂移校正指数提高了约 60%，这证实了部分多项式校正方法在解决畸变问题方面具有普遍适用性和高效性。

Image distortion correction based on partial polynomial model for a large-array photon-counting detector

A microchannel plates (MCPs) photon-counting detector with a cross-delay line (XDL) is expected for high-quality and wide-field target imaging. However, it is a great challenge for the uniformity of system response as the increasing of effective detection area. In this article, we develop a XDL photon-counting detector with a wide field of 120 mm × 50 mm. Additionally, we investigate the origin of image distortion and propose a partial polynomial correction method to alleviate it. The experimental results show that the drift correction index is improved by around 60% under the proposed method, which confirms that the partial polynomial correction method has general applicability and high efficiency in addressing distortion issues.
