Paper Abstract

Pyroelectric infrared sensor arrays are imaging devices for infrared radiation that utilize the temperature dependence of the remanent polarization in pyroelectric materials. An analytic calculation of the modulation transfer function of a pyroelectric sensor array was carried out for a simplified model. More realistic models, however, require the use of numerical methods like the finite element method. We present a method to derive the modulation transfer function from simulation data of a finite-element model and compare the results of the analytic and numerical calculations for a test model.
