S. Karpov, A. Bajat, A. Christov, M. Prouza

AI总结:

本研究评估了Andor Marana sCMOS相机在宽视场巡天中的性能,通过实验室测试和在轨测试验证了其时间稳定性、线性度及天文应用潜力。

摘要:

科学CMOS图像传感器是典型CCD探测器的现代替代品,兼具低读出噪声、大感光面积和高帧率的优势。这些特点使其成为现代宽视场巡天的理想设备。然而,在分析数据时必须妥善考虑CMOS技术的特殊性。为了表征这些特性,我们对Andor Marana sCMOS相机进行了广泛的实验室测试。在此我们报告测试结果,特别是在时间稳定性和线性度方面,并将其与旧版本的Andor sCMOS相机进行比较。我们还展示了该传感器连接宽视场镜头的在轨测试结果,并探讨其在天文巡天中的应用。

英文摘要:

Scientific CMOS image sensors are a modern alternative for a typical CCD detectors, as they offer both low read-out noise, large sensitive area, and high frame rates. All these makes them promising devices for a modern wide-field sky surveys. However, the peculiarities of CMOS technology have to be properly taken into account when analyzing the data. In order to characterize these, we performed an extensive laboratory testing of Andor Marana sCMOS camera. Here we report its results, especially on the temporal stability and linearity, and compare it to the previous versions of Andor sCMOS cameras. We also present the results of an on-sky testing of this sensor connected to a wide-field lens, and discuss its applications for an astronomical sky surveys.
