Infrared Detector Butted Technology for Space

To meet the demand for wide field of view, high-resolution, and multispectral detection in space applications, more large-scale bands and infrared focal plane arrays will be the future trend in space remote sensing. Currently, the scale and band of massive array detectors are limited by the sizes of detector materials and processing technology of silicon; thus, they are unable to meet the space requirements for wide field of view, high-resolution, and multispectral detection. Obtaining large-scale and multiband detectors through butting is a practical solution. In this paper, several butting techniques are discussed, and their properties, key technologies, and capabilities are presented.
