摘要:

利用光子重定格式器消除常规模式噪声的影响,可以大大提高高分辨率摄谱仪的稳定性。然而,这种优势变得明显的制度尚未确定。在这里,我们将看看模态噪声在传统的高分辨率光谱学中成为一个问题,以及光子光谱仪可能产生的影响。我们将从理论上推导出可实现的径向速度测量比较光子仪器和传统的。我们将讨论优化和证明光子重整概念所需的理论和实验研究。

英文摘要:

Using a photonic reformatter to eliminate the effects of conventional modal noise could greatly improve the stability of a high resolution spectrograph. However the regimes where this advantage becomes clear are not yet defined. Here we will look at where modal noise becomes a problem in conventional high resolution spectroscopy and what impact photonic spectrographs could have. We will theoretically derive achievable radial velocity measurements to compare photonic instruments and conventional ones. We will discuss the theoretical and experimental investigations that will need to be undertaken to optimize and prove the photonic reformatting concept.
