摘要
我们提出了面向远红外天文学探针计划(PRIMA)的 Far-Infrared Enhanced Survey Spectrometer(FIRESS)的体系结构概念。FIRESS 覆盖 24--235 微米范围,包含四个 R ~ 100 的狭缝馈入光栅模块,每个模块耦合到 24(空间)×84(光谱)像素的动力学电感探测器(KID)阵列。所有四个阵列同时读取,感兴趣的点源可同时耦合到两个波段。Fourier 变换模块可在 FIRESS 狭缝的部分区域启用,以创建高分辨率模式,在该模式下,光线被截获、经干涉仪处理后重新注入到光栅模块的路径中进行探测。我们提供了用于获取高分辨率光谱的技术模拟与描述。我们确定由探测器系统施加的最重要系统要求,并指出这些要求是通过现有设计实现的。最后,我们提出了我们的性能建模,包括基于当前设计状态的直接估计,以及为开发通用观察者程序提供持久指导。
