作为未来红外探测器的主流发展方向之一，大面阵红外探测器近年来的发展非常迅速，主要用于天体物理学、地球科学和行星科学等领域，并且是未来地球天气与气候描述、空气污染检测方面的一种主要工具。随着面阵规格和材料尺寸的增加，器件的制作难度也越来越大。重点介绍了目前国际上最常见的两种制冷型红外探测器——HgCdTe和InSb红外探测器。结合国内外的一些文献，总结了这两种红外探测器的大面阵技术的发展状况，并重点介绍了当前全球行业领先的几家红外探测器厂商的相关产品及技术水平。最后指出了大面阵红外探测器研制目前存在的主要问题。

As one of the mainstream development directions of future infrared detectors, large-format infrared detectors have developed very rapidly in recent years. They are mainly used in the fields such as astrophysics, earth science, and planetary science. They are also a major tool for earth′s weather and climate description and air pollution detection in the future. With the increase of array format and material size, the difficulty of making devices has become more and more difficult. The two most commonly used infrared detectors in the world—HgCdTe and InSb infrared detectors—are introduced. Based on some domestic and foreign literatures, the development of the large-area-array technology of these two infrared detectors is summarized, and the relevant products and technical levels of several leading infrared detector manufacturers in the global industry are highlighted. Finally, the main problems in the development of large-format infrared detectors are pointed out.
