| Abstract: | Designed uncooled infrared imaging components, to achieve infrared imaging. First, in- troducing the hardware design of uncooled infrared imaging components. For such a weak infrared signal acquisition, reducing noise is key for the analog circuits. Flexible design is its advantages. In software, real-time achieving the nonuniformity correction of infrared image. And according to the characteristics of infrared imaging, designing image enhancement method based on ＂the temperature window＂, which is suitable for hardware implementation. The components through the communication interface can change working conditions. Finally, providing of test method and test indicators of infrared imaging compo- nents, and proving infrared imaging very good to meet the design requirements. |
