| dc.description.abstract | 在可見光高解析成像技術中，幸運成像法是相對較不昂貴的方法。在中央大學天文所，這是第一次對幸運成像法做相關研究。我們利用一臺商售級CMOS相機ASI294MM-Pro，於鹿林一米鏡實行幸運成像法。在這篇論文中，我們致力於將相機的效能與解析力最佳化。在影像品質排序法上，我們開發利用”Ip” 來對影像銳利度評比。實驗在視寧度1.4 角秒的條件下執行，從1 至100% 最佳影像中，系統的星點改善因子為1.98 至1.25。而在與蓋亞星表比對後，顯示星點位置的誤差為ΔRA=−0.04±0.09”, ΔDEC=−0.02±0.09”。 | zh_TW |
| dc.description.abstract | Lucky imaging (LI) is an relatively inexpensive way to achieve high-resolution in visible light. This is our first time to study LI technique at the Lulin observatory by using a commercial-grade CMOS camera ASI294MM-Pro on Lulin One-meter Telescope. In this thesis, we focus on optimizing the camera’s performance on astrometric measurements. In frame-selection, we developed our method by measuring the quantity ”Ip” to sort the frame sharpness. The result shows the full width at half-maximum can be improved by a factor of 1.98-1.25 among 1 to 100%-selection under 1.4” seeing. When matched to Gaia DR3 catalog, the positional error is found to be ΔRA = −0.04 ± 0.09”, and ΔDEC = −0.02 ± 0.09” within 1.6’×1.6’ field of view. | en_US |
