Infrared detectors are the core components of space infrared early warning satellites. With the continuous improvement of infrared detector performance,the use of larger and more spectral infrared detector focal plane array is the development trend of infrared detectors for early warning in the future. The infrared detector with longer line scale is prepared by multi chip and multi spectrum integration splicing to meet the large market,high resolution and multi spectral detection capability of infrared early warning satellites. In this paper,the development status and technical route of multi chip and multi spectrum splicing infrared detector components at home and abroad are compared,and the application prospects of miniaturized splicing detectors in other fields are prospected. Finally,the main problems existing in the development of large size splicing infrared detectors are pointed out.
