| Summary: | 碩士 === 國防大學中正理工學院 === 兵器系統工程研究所 === 94 === With the development of infrared technology, infrared system of all sorts of design has already been extensively used in military, industry, medical science and science research. It gives better accuracy and easy of use for Non-destructive testing, environmental monitoring, air monitoring and so on. Especially for military application, thermal imaging research has received noticeable attention for every nation.
The night vision equipment has become indispensable weapons in today’s battlefield, which is critical for winning the battle at day and night. There are majorly three catagories of night vision equipments developed that are infra-periscope, night vision goggle and thermal imaging system. However, only the last two types are still in service. Specially for thermal imaging system, which has some characteristics as passive in nature, no fear of strong light, good penetration of smog and dust, and good camouflage ability compared to visible light. The thermal imaging system is still much expensive compared to the night vision google. However with the fast development of thermal imaging technology, the manufacture cost is hoped to be down and more popular used.
In this paper, we will study the imaging performance factors of an infrared system by using the Infrared radiation theorem. In addition, an opto-mechanical system of a tank thermal imager will be rebuilt by using the concept of optical system design and computer simulation, to examine the critical factors of imaging quality. The simulation results were also studied to give better understanding of the imaging system evaluation and analyze, and providing references for future weapon design.
