AI中文摘要：
体光学天文光谱仪的线性尺寸随对应望远镜主镜直径成比例增大。随着现代望远镜口径不断增加，光谱仪的小型化除了具备多功能集成和光子效率方面的优势外，还变得至关重要。本文提出的紧凑型阵列波导堆叠多目标光谱仪（CAWSMOS）的研制方案包括阵列波导光栅（AWG）芯片、堆叠框架以及用于对每个AWG的多个光谱级次成像的交叉色散光学元件的设计，旨在降低天文光谱仪的成本和尺寸，同时提高效率，这将使AWG技术更接近其在地基、机载和天基天文应用中全部潜力的实现。该研制工作的一部分是对波茨坦阵列波导光谱仪（PAWS）的扩展，为此将Zemax模型与PAWS校准数据进行对比，发现位置在x方向28像素、y方向18像素的范围内可与测量值匹配；还发现测量的点扩散函数（PSF）尺寸与Zemax模型存在约5倍的差异，且探测器区域仅能部分容纳第二个芯片。
英文摘要：
The linear size of a bulk optical astronomical spectrograph scales with the diameter of the primary mirror of the corresponding telescope. As modern telescopes continue to increase in aperture size, miniaturization of the spectrograph becomes crucial beyond the offered advantages in terms of multifunctional integration and photon efficiency. The presented concept of development for a Compact Arrayed Waveguide Stacked Multi-Object Spectrograph (CAWSMOS) includes the design of the Arrayed Waveguide Grating (AWG) chips, the stacking frame and cross-dispersion optics for the imaging of multiple spectral orders per AWG. It aims to reduce the cost and size of astronomical spectrographs while also improving efficiency. This will bring the AWG technology closer to the realization of its full potential for ground based, airborne and spaceborne astronomical applications. Part of this development is an extension of the Potsdam Arrayed Waveguide Spectrograph (PAWS). To do that, the Zemax model is compared to PAWS calibration data, finding that the position can be matched with the measurement within 28 px in x and 18 px in y-direction. It also shows a discrepancy between the measured PSF size and the Zemax model of around factor five, and that the detector area can only partially accommodate a second chip.
