Abstract
An attempt was made to obtain a simple Laplace transfer function model of a pyroelectric detector which would make an excellent basis for the analysis of its dynamic behaviour. Knowledge of the transfer function model of the pyroelectric detector is necessary for its simulation studies in MATLAB/Simulink environment. A simple model of the pyroelectric detector was implemented in MATLAB/Simulink and some exemplary results of investigation of its voltage response to incident radiation and frequency characteristics were presented.
