The combined evaluation of the thermal and electrical domain of a pyroelectric system is a challenging task. The proposed approach precisely models the thermal system with FEM. The output data is approximated with a fit function and transferred to SPICE creating a universal and adaptable model for the whole pyroelectrical signal chain. For validation, the InfraTec detector LRM-244 is used.
