Aiming at problem that traditional uncooled infrared imaging system which based on DSP + FPGA has many disadvantages such as large volume

high power consumption

poor real-time performance

low system integration

and so on

a design of miniaturized uncooled infrared imaging system based on FPGA is proposed. The design aims at 25 μm uncooled infrared detector. The latest FPGA processor and DDR3 memory technology are adopted to meet the requirement of miniaturization and low power consumption. A novel solution of combination of hardware logic algorithm and NIOS Ⅱsoft core architecture is proposed. By this way

complete timing driving of infrared detector

temperature control

non-uniformity processing of image

image enhancement

man-machine interface control. Experimental results show the system owns characteristics of higher imaging quality

power consumption of system is less than 2 W

system delay is less than 0. 5 ms and the system can be easy extended.
