Design of the data acquisition and real-time imaging system for UIRFPA

This paper presents a useful design of the time-series driving, data acquisition and real-time imaging system for the uncooled infrared focal plane arrays (UIRFPA). The field programmable gate array (FPGA) is used as the central processing unit (CPU) in the system, which can control and harmonize all functional modules. The Ping-Pong structure is employed to realize real-time imaging. The SDRAM is adopted for the data storage to fulfill the need of mass memory. And there are also some switches and keys to provide human-machine interaction. This system works for UIRFPA with resolution of 320x240 steadily and authoritatively. The noise doesn't merge in main signals, so the system can extract the signals of UIRFPA accurately and efficiently.
