高性能制冷型红外焦平面读出电路研究进展OA

Infrared imaging technology,as a core technology in modern information-based equip-ment systems,has been widely applied in military reconnaissance,target surveillance,security moni-toring,aerospace exploration,and precision guidance.As a key component of infrared imaging sys-tems,the focal plane readout array plays a crucial role in determining the quality of the acquired infra-red images,and research on its architecture and technical routes has become an important driving force for performance improvement in infrared imaging systems.In recent years,with the continuous expansion of infrared detector array scales and the increasing demand for intelligent processing and fast response in imaging systems,the design of cooled infrared focal plane readout integrated circuits has achieved significant progress in terms of architectural innovation and performance optimization.This paper reviews the current development status of cooled infrared focal plane readout circuits,sys-tematically summarizes recent domestic and abroad researches progress from four aspects:high dynamic range readout technique,event-driven readout technique,multispectral readout technique,and other emerging readout techniques.Finally,it discusses the future development trends of cooled infrared focal plane readout circuits.
