Tomo-e Gozen 相机是新一代超广角光学相机，配备 84 个 CMOS 传感器。相机以 2 Hz 的频率记录约 20 平方度的区域，提供“天文电影数据”。我们开发了 Tomo-e Gozen 相机原型（以下简称 Tomo-e PM），以评估 Tomo-e Gozen 相机的基本设计。 Tomo-e PM配备8个CMOS传感器，能够以高达2 Hz的频率捕获2平方度的区域。每个 CMOS 传感器大约有 260 万像素。 Tomo-e PM 的数据速率约为 80 MB/s，相当于约 280 GB/小时。我们开发了操作系统和缩减软件来处理如此大量的数据。 Tomo-e PM 安装在东京大学木曾天文台的 1.0 米施密特望远镜上。于2015年冬季和2016年春季进行了实验观测，顺利完成了观测和软件实现。数据缩减现在正在执行。
The Tomo-e Gozen camera is a next-generation, extremely wide field optical camera, equipped with 84 CMOS sensors. The camera records about a 20 square degree area at 2 Hz, providing “astronomical movie data”. We have developed a prototype of the Tomo-e Gozen camera (hereafter, Tomo-e PM), to evaluate the basic design of the Tomo-e Gozen camera. Tomo-e PM, equipped with 8 CMOS sensors, can capture a 2 square degree area at up to 2 Hz. Each CMOS sensor has about 2.6 M pixels. The data rate of Tomo-e PM is about 80 MB/s, corresponding to about 280 GB/hour. We have developed an operating system and reduction softwares to handle such a large amount of data. Tomo-e PM was mounted on 1.0-m Schmidt Telescope in Kiso Observatory at the University of Tokyo. Experimental observations were carried out in the winter of 2015 and the spring of 2016. The observations and software implementation were successfully completed. The data reduction is now in execution.
