In this paper, we present a comprehensive calculational model for the noise equivalent temperature difference (NETD) of infrared imaging systems based on uncooled bolometer arrays. The equations are presented in a new and convenient form. The NETD model is validated and benchmarked using published performance data of a state-of-the-art uncooled infrared bolometer array. The NETD model is used to evaluate possible system and bolometer design improvements. The results of the calculations suggest that infrared imaging systems based on uncooled bolometer arrays with a bolometer pixel pitch of 28 mu m x 28 mu m have the potential to reach NETDs on the order of 12 mK. The calculations also suggest that NETDs on the order of 200 mK can be achieved with infrared imaging systems based on uncooled bolometer arrays that operate in air at atmospheric pressure.
