Abstract
With the development of thermal imaging, more and more applications are mentioned not in military, but also commercial such as industry monitoring, automobile nightvision, far distance medicine care etc. In infrared thermal imaging, infrared optics system, sensing focal plane arrays and signal processing circuit are intensively researched. The sensing focal plane is very important one. Generally, focal plane arrays are classified as cooled and uncooled. Due to the advantages of low cost and small volume, and the performance is afford to generally commercial applications, we focus on uncooled infrared sensing focal plane array. In all type of uncooled infrared technique, microbolometer is an important one. The microbolometer generates the signals with the resistance changed by temperature difference, hence, the thin film sensing material needs high temperature coefficient of resistance to get larger signal from small temperature difference. In this thesis, we investigated a new sensing material – cytochrome c. By measuring the resistance varies with temperature, we proved the high temperature coefficient of resistance of thin film. And we proposed a new structure composed by SU8 and simulated the responsivity of it. We hoped this method provides a solution for low cost thermal imaging system.
