我们描述了用于SIRTF的多波段成像光度计(MIPS)的地面测试和表征。该仪器是一种具有三个焦平面阵列的相机，覆盖以24μm、70μm和160μm为中心的宽光谱波段。该仪器具有多种工作模式，可实现精确测光、衍射限制成像、高效测绘和低分辨率光谱能量分布测定。MIPS的观测理念在很大程度上依赖于频繁使用内部相对校准源以及数据收集中的高度冗余。我们表明，通过使用这种方法，MIPS的用户可以期待对天文来源进行非常敏感、高度重复的观测。MIPS的地面特性计划涉及许多设施，包括用于焦平面水平测试的测试杜瓦，用于仪器水平测试的专门低温恒温器，以及飞行SIRTF低温望远镜组件的测试
We describe the ground testing and characterization of the Multiband Imaging Photometer for SIRTF (MIPS). This instrument is a camera with three focal plane arrays covering broad spectral bands centered at 24 μm, 70 μm, and 160 μm. The instrument features a variety of operation modes that permit accurate photometry, diffraction-limited imaging, efficient mapping, and low resolution spectral energy distribution determinations. The observational philosophy of MIPS relies heavily on the frequent use of internal relative calibration sources as well as a high level of redundancy in the data collection. We show that by using this approach, users of MIPS can expect very sensitive, highly repeatable observations of astronomical sources. The ground characterization program for MIPS involved a number of facilities including test dewars for focal-plane level testing, a specialized cryostat for instrument-level testing, and tests in the flight SIRTF Cryo-Telescope Assembly
