Abstract :
Pyroelectric infrared sensor arrays are imaging devices for infrared radiation that utilise the temperature dependency of the remanent polarisation in pyroelectric materials. We use the finite element method (FEM) for the calculation of the coupled thermo-electro-mechanical fields for a 3D sensor model. From the simulation data we derive the modulation transfer function.
