光子摄谱仪可以比具有相同分辨率的传统摄谱仪小得多。个别装置可以与光纤集成,以提高天文光谱学中的多路复用增益。虽然实验设备已经过测试,集成光子光谱仪提供显着的优势,比传统方法的参数空间还没有被定义。本文给出了一个概述的理论与验证直接模拟使用菲涅尔传播和量化的代表性光谱能力的好处。因此,我们确认了光子光谱仪的优势,特别是下一代超大型望远镜,并得出结论,这些设备可能是重要的天文仪器的未来发展。
A photonic spectrograph can be much smaller than a conventional spectrograph with the same resolving power. Individual devices can be integrated with optical fibres to improve the multiplex gain in astronomical spectroscopy. Although experimental devices have been tested, the parameter space where integrated photonic spectrographs offer significant advantage over traditional methods has not been defined. This paper gives an overview of the theory with verification by direct simulation using Fresnel propagation and quantifies the benefit for representative spectroscopic capabilities. We thereby confirm the advantage of photonic spectrographs, especially to the next generation of extremely large telescopes, and conclude that these devices may be important for the future development of astronomical instrumentation.
