Designs of driving module and signal processing module of VOx IRFPA

Abstract

Compared with the infrared focal plane array (IRFPA) based on amorphous silicon (α-Si), IRFPA based on vanadium oxide (VOx) has the advantages of big temperature coefficient, low noise and so on. Therefore, it is believed that VOx IRFPA has important application in both military and civil field. In this paper, the designs of driving module and signal processing module of VOx IRFPA are proposed. Firstly, the hardware designs of the driving module and signal processing module of VOx IRFPA are discussed in detail. Secondly, the design of the system configuration programs based on FPGA are introduced. Finally, some experiments were carried out to verify the validity of the developed modules, the results indicated that our work will lay a foundation for the implement of micro and low-cost infrared imaging system, and promote the application of infrared imaging technology in the field of civil consumption.
