Hyper Suprime-Cam（HSC）是位于夏威夷莫纳克亚山山顶的8.2米斯巴鲁望远镜主焦点上的宽视场成像相机。来自日本、台湾和普林斯顿大学的科学家团队正在使用HSC对高纬度天空进行300个夜晚的多波段成像调查。该调查包括三个层：Wide层将覆盖1400 deg（2）的五个宽带（Grizy），5 sigma点源深度r约为26。Deep层在四个区域中总共覆盖了26度（2），大约暗了一个星等，而UltraDeep层在HSC的两个点中几乎仍然暗了一个星等（总共3.5度（2））。在这里，我们描述了仪器，调查的科学目标，调查策略和数据处理。本文是《日本天文学会出版物》特刊的导言，其中包括大量描述这一调查早期阶段结果的技术和科学论文。
Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2-m Subaru telescope on the summit of Mauna Kea in Hawaii. A team of scientists from Japan, Taiwan, and Princeton University is using HSC to carry out a 300-night multi-band imaging survey of the high-latitude sky. The survey includes three layers: the Wide layer will cover 1400 deg(2) in five broad bands (grizy), with a 5 sigma point-source depth of r approximate to 26. The Deep layer covers a total of 26 deg(2) in four fields, going roughly a magnitude fainter, while the UltraDeep layer goes almost a magnitude fainter still in two pointings of HSC (a total of 3.5 deg(2)). Here we describe the instrument, the science goals of the survey, and the survey strategy and data processing. This paper serves as an introduction to a special issue of the Publications of the Astronomical Society of Japan, which includes a large number of technical and scientific papers describing results from the early phases of this survey.
