128×128 element Hybrid Uncooled Pyroelectric IR FPA,which was developed by Kunming Institute of Physics,was introduced in this paper.First,the national and oversea development of Hybrid Uncooled Pyroelectric IR FPA and hybrid structure was used in the FPA were presented,then the key factor that effected on the FPA′s performance was analyzed.Not only were the material′s electrics and physical characteristic that were applied in the FPA,but also heat isolation structure and ROIC technology were discussed.Some IR explicit picture getting from the IR FPA was given.At last,experimentation result and some methods that improving performance was applied in the future were discussed and analyzed.
