1 μm ~ 2 μm漫辐射的绝对分光光度测量对于我们理解宇宙再电离以来核合成的辐射含量、太阳系黄道尘埃云的组成和结构以及星际尘埃散射星光产生的银河漫光至关重要。火箭载宇宙红外背景实验低分辨率光谱仪（LRS）是一台λ/Δλ = 15-30的绝对分光光度计，用于精确测量0.75 μm< λ< 2.1 μm的绝对近红外天空亮度。本文介绍了LRS的光学、机械和电子设计，以及飞行前为验证其性能而进行的地面测试、表征和校准测量。LRS的工作规范，实现必要的光学和灵敏度性能。我们描述了我们的理解和控制的系统误差源的绝对测光的河外近红外背景光。
Absolute spectrophotometric measurements of diffuse radiation at 1 μm to 2 μm are crucial to our understanding of the radiative content of the universe from nucleosynthesis since the epoch of reionization, the composition and structure of the zodiacal dust cloud in our solar system, and the diffuse galactic light arising from starlight scattered by interstellar dust. The Low Resolution Spectrometer (LRS) on the rocket-borne Cosmic Infrared Background Experiment is a λ/Δλ∼ 15–30 absolute spectrophotometer designed to make precision measurements of the absolute near-infrared sky brightness between 0.75 μm< λ< 2.1 μm. This paper presents the optical, mechanical, and electronic design of the LRS, as well as the ground testing, characterization, and calibration measurements undertaken before flight to verify its performance. The LRS is shown to work to specifications, achieving the necessary optical and sensitivity performance. We describe our understanding and control of sources of systematic error for absolute photometry of the near-infrared extragalactic background light.
