An Approach for Thermal Modelling of Uncooled Infrared Bolometer Detector Arrays Including Noise Equivalent Temperature Difference (NETD) Prediction

In this paper, we proposed an approach for analyzing uncooled infrared bolometer arrays, considering temperature dependence of Thermal Coefficient of Resistance (TCR). Calculations were carried out using an equivalent thermal circuit. Eventually, the Noise Equivalent Temperature Difference (NETD) including the contributing NETD parts is obtained as figure of merit. By this analysis, we achieved a reliable method to estimate the performance of bolometer detector in comparison with experimental cases.
