Abstract:In this paper we presented a model for the noise equivalent temperature difference(NETD)of infrared imaging systems based on uncooled microbolometer arrays.According to calculational model we designed the pixel structure of uncooled microbolometer arrays.Then.several results Of the analysis of the stress and displacement are presented using FEA (Finite Element Analysisl in this paper.According to this result we have got an optimal design of the pixel structure.
Keywords:Finite Element Analysis (FEA)  uncooled microbolometer arrays  stress
