Near-Infrared Mosaic Camera

在这项研究中，我们构建了一个具有两个2048 x 2048 HgCdTe阵列的近红外马赛克相机，用于0.8至2.5 μm波长的宽视场成像。TUFPAC （Tohoku University焦平面阵列控制器）是专为2048 x 2048 HgCdTe （HAWAII-2）阵列灵活控制和高效数据采集而设计的阵列控制系统。在Linux操作系统的个人计算机上，通过安装在PCI总线上的DSP板控制马赛克HAWAII-2s。使用TUFPAC，我们广泛检查了安装在专门为测试设计的测试杜瓦中的阵列的性能（稳定性、读出噪声、线性度和暗噪声）。该马赛克相机将安装在多目标近红外摄谱仪（MOIRCS）上，该多目标近红外摄谱仪将与国家天文台的SUBARU望远镜一起用于高红移星系演化和星系团结构形成的研究。

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.
