In this research, we have constructed a near-infrared mosaic camera with two 2048 x 2048 HgCdTe arrays for wide field imaging at 0.8 to 2.5 μm wavelengths. TUFPAC (Tohoku University Focal Plane Array Controller) is an array control system specifically designed for flexible control and efficient data acquisition for 2048 x 2048 HgCdTe (HAWAII-2) array. A personal computer operated by Linux OS controls mosaic HAWAII-2s with DSP boards installed on the PCI bus. Using TUFPAC, we have extensively examined the performance (stability, read-out noise, linearity, and dark noise) of the arrays installed in a test dewar specifically designed for the test. The mosaic camera will be installed to multi-object near-infrared camera and spectrograph (MOIRCS), which is supposed to be used with SUBARU telescope at National Astronomical Observatory for the study of galaxy evolution and structural formation of clusters at high redshift.

在本研究中，我们已经建立了一个近红外镶嵌相机与两个2048 × 2048碲镉汞阵列的宽视场成像在0.8至2.5 μm波长。TUFPAC（Tohoku University Focal Plane Array Controller）是一个阵列控制系统，专门为2048 x 2048 HgCdTe（夏威夷-2）阵列的灵活控制和高效数据采集而设计。由Linux操作系统操作的个人计算机控制镶嵌夏威夷-2，DSP板安装在PCI总线上。使用TUFPAC，我们已经广泛地检查了安装在专门为测试设计的测试杜瓦瓶中的阵列的性能（稳定性，读出噪声，线性度和暗噪声）。镶嵌相机将安装到多目标近红外相机和光谱仪（MOIRCS），该相机将与国家天文台的SUBARU望远镜一起用于研究星系演化和高红移星系团的结构形成。
