论文摘要
切片机与用于外球星光谱的镜头阵列（尺度）是一种仪器，是一种仪器，旨在使用W.M的自适应光学系统在中红外（2-5μm）中直接对外球星进行直接成像。凯克天文台。为了消除不需要的热红外辐射，尺度既利用了冷脚，也可以排除背景辐射，又要使用lyot停止的矢量涡流coronagraph进行星光抑制。已经设计了最佳的几何面罩。我们通过Lyot平面模拟光的传播，并分析K，L和M带中恒星的轴上图像，以制定Lyot停止的性能。此外，提出了最终确定的冷站和Lyot停止设计，并评估制造公差和由轴心抛物线镜镜继电器引起的瞳孔平面中的倾斜度的影响。
The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES) is an instrument being designed to perform direct imaging of exoplanets in the mid-infrared (2-5 μm) with the Adaptive Optics System of W.M. Keck Observatory. To eliminate unwanted thermal infrared radiation, SCALES utilizes both a cold stop for excluding background radiation and a vector vortex coronagraph with Lyot stops for starlight suppression. Optimal geometric masks have been designed. We simulate the propagation of light through the Lyot plane and analyze the on-axis images of stars in the K, L, and M band for the performance of the Lyot stops. Additionally, finalized cold stop and Lyot stop designs are presented along with evaluations on the effects of manufacturing tolerances and tilt in pupil planes caused by off-axis parabolic mirror relays.
