标题： Commissioning of a Commercial CMOS Camera for the Application of Lucky Image Technique on the Lulin One-meter Telescope

摘要： 幸运图像（LI）是一种技术，旨在实现接近衍射极限的高角分辨率图像，适用于一米级光学望远镜。 在这项工作中，通过观测球状星团M15的核心，我们展示了LI技术可以应用于一米级望远镜，即芦林一米望远镜（LOT），以及使用商用级CMOS相机。 我们还开发了一种方法，通过测量选定参考星的每像素平均强度来对LI帧的质量进行排序。 对于基于最佳10%选择帧重构的LI图像，我们在半高全宽（FWHM）上比传统的长时间曝光图像提高了$1.7\times$。 当将LI重构图像上的检测源与Gaia数据发布3目录进行交叉匹配时，我们得到了右 ascension 方向上 $-0.04\pm0.09$" 和 declination 方向上 $-0.02\pm0.09$" 的平均差异，同时达到了Gaia $G$带中的 $\sim 17.9$ 魔力深度 $5\sigma$。 显示英文摘要

摘要： Lucky image (LI) is a technique to achieve near diffraction-limit high-angular resolution images for meter-class optical telescopes. In this work, by observing the core of globular cluster M15, we demonstrated the LI technique can be applied to a 1-meter telescope, the Lulin One-meter Telescope (LOT), together with a commercial-grade CMOS camera. We have also developed a method to sort the quality of the LI frames by measuring the mean intensity per pixel on the selected reference stars. For a LI-reconstructed image based on the best 10\%-selected frames, we achieved a $1.7\times$ improvement on the full-width at half-maximum over the conventional long-exposure image. When cross-matched the detected sources on the LI-reconstructed image to the Gaia Data Release 3 catalog, we obtained a mean difference of $-0.04\pm0.09$" and $-0.02\pm0.09$" on the right ascension and declination, respectively, as well as reaching to a $5\sigma$ depth of $\sim 17.9$ mag in the Gaia $G$-band.
