JEM-EUSO（日本实验舱极端宇宙空间观测站）是一个先进的观测站，将在国际空间站（ISS）上使用地球大气层作为巨大的热量计探测器。然而，大气云在JEM-EUSO测量的信号中引入了不确定性。因此，了解望远镜视场（FoV）内的大气状况和云的性质是非常重要的。JEM-EUSO的大气监测系统（AMS）包括一个激光雷达和一个红外成像系统（IR相机），目的是在JEM-EUSO主望远镜观测期间探测云的存在并获得云覆盖率和云顶高度。为了确定电子设计的路线图，探测器已经用第一个原型进行了广泛的测试。本文介绍了红外相机的实际设计，原型的测试，以及这种表征的结果。
JEM-EUSO (Extreme Universe Space Observatory on Japanese Experiment Module) is an advanced observatory that will be on-board the International Space Station (ISS) and use the Earth׳s atmosphere as a huge calorimeter detector. However, the atmospheric clouds introduce uncertainties in the signals measured by JEM-EUSO. Therefore, it is extremely important to know the atmospheric conditions and properties of the clouds in the Field of View (FoV) of the telescope. The Atmospheric Monitoring System (AMS) of JEM-EUSO includes a lidar and an infrared imaging system, IR-Camera, aimed to detect the presence of clouds and to obtain the cloud coverage and cloud top altitude during the observations of the JEM-EUSO main telescope. To define the road-map for the design of the electronics, the detector has been tested extensively with a first prototype. The actual design of the IR-Camera, the test of the prototype, and the outcome of this characterization are presented in this paper.
