Abstract

Compared with the infrared focal plane array (IRFPA) based on amorphous silicon (α-si), IRFPA based on vanadium oxide (VO_x) has the advantages of big temperature coefficient of resistance, low noise and so on. In this paper, the design of the micro uncooled infrared imaging system based on VO_x IRFPA is introduced. Firstly, the hardware design of the proposed system is discussed, which includes the system structure, VO_x IRFPA module, driving module and the signal processing module based on FPGA. Secondly, the designs of the system configuration program as well as the consistency correction of the proposed system are discussed. Finally, some experiments were carried out to verify the validity of the models and the whole infrared imaging system, which indicated that our work will lay a foundation for the implement of micro and low-cost infrared imaging system.
