SCALES贸易研究的信息量方法
Information Content Approach to Trade Studies for SCALES
摘要：
具有高保真仪器仿真工具与新型仪器一起开发的优点是能够单独和组合地研究由仪器设计设置的宽参数空间。SCALES是为Keck设计的第三代热红外衍射极限成像仪和低/中分辨率积分场摄谱仪，是一种独特的设计，以优化其直接探测和表征冷系外行星热发射的驱动科学案例。这保证了一个端到端的模拟工具，系统地产生现实的模拟数据从规模探测仪器设计参数的变化下注入信号的恢复。在本文中，我们量化的光学机械公差和探测器的电子要求所设定的基准科学的情况下，使用信息内容分析，并测试的后果更新的仪器的设计，以满足这些要求。
英文摘要：
The advantage of having a high-fidelity instrument simulation tool developed in tandem with novel instrumentation is having the ability to investigate, in isolation and in combination, the wide parameter space set by the instrument design. SCALES, the third generation thermal-infrared diffraction limited imager and low/med-resolution integral field spectrograph being designed for Keck, is an instrument unique in design in order to optimize for its driving science case of direct detection and characterization of thermal emission from cold exoplanets. This warranted an end-to-end simulation tool that systematically produces realistic mock data from SCALES to probe the recovery of injected signals under changes in instrument design parameters. In this paper, we quantify optomechanical tolerance and detector electronic requirements set by the fiducial science cases using information content analysis, and test the consequences of updates to the design of the instrument on meeting these requirements.
