Abstract

We report on an advanced simulator facility to model reliably the performance of complete pyroelectric detector (PED) systems. The temperature distribution in the pyroelectric chip is modelled by the finite element method and verified by a separate measurement with a commercial PED. From the temperature transients, the pyroelectric effect and transimpedance conversion are modeled on a time scale much finer than the PED response time, accommodating a large variety of time-dependent radiative load scenarios. The voltage output of the PED is fed into the signal processing algorithm of choice, allowing to investigate the conditions for maximizing the signal to noise ratio.
