Astronomical IRFPA Image Collecting System Based on the NiosⅡ Soft-core Embedded Processor

An Astronomical Infrared Image Collecting System based on the IRFPA(Infrared Focal Plane Array) is introduced.The principle and character of the IRFPA is describled.It is focused on the discussing the electronic system architecture of the IRFPA Image Collecting System.The hardware and software design is built up based on the Nios ?? soft-core processor.Finally two Infrared images acquired by the IRFPA image collecting system is analysed.It is shown that the electronic system design for the IRFPA System can be used for the astronomical observation.
