SMI（SPICA中红外仪器）是新SPICA计划的两台焦平面科学仪器之一，也是由日本大学财团提出和管理的日本仪器。 SMI 覆盖 12 至 36 μm 的波长范围，使用以下三个具有前所未有的高灵敏度的光谱通道：低分辨率光谱（LRS；R = 50 - 120、17 - 36 μm）、中分辨率光谱（MRS；R = 1300 - 2300、18 - 36 μm）和高分辨率光谱（HRS；R = 28000、 12 - 18 微米）。这些通道的关键功能是使用 LRS 进行高速尘带测绘、使用 MRS 进行高灵敏度多用途光谱测绘以及使用 HRS 进行高分辨率分子气体光谱测绘。本文介绍了SMI的技术理念和科学能力。
SMI (SPICA Mid-infrared Instrument) is one of the two focal-plane scientific instruments planned for new SPICA, and the Japanese instrument proposed and managed by a university consortium in Japan. SMI covers the wavelength range of 12 to 36 μm, using the following three spectroscopic channels with unprecedentedly high sensitivities: low-resolution spectroscopy (LRS; R = 50 - 120, 17 - 36 μm), mid-resolution spectroscopy (MRS; R = 1300 - 2300, 18 - 36 μm), and high-resolution spectroscopy (HRS; R = 28000, 12 - 18 μm). The key functions of these channels are high-speed dustband mapping with LRS, high-sensitivity multi-purpose spectral mapping with MRS, and high-resolution molecular-gas spectroscopy with HRS. This paper describes the technical concept and scientific capabilities of SMI.
