摘要

W artykule zaprezentowano rozważania analityczne mające na celu opracowanie modelu transmitancyjncgo detektora piroelektrycznego. Model ten zaimplemenlowano w środowisku MATLAB-Simulink w celu realizacji badań symulacyjnych tego detektora. Pokazano kilka przykładowych wyników badań odpowiedzi napięciowej na pobudzenia promieniowaniem o różnych kształtach przebiegu czasowego.%In the paper analytical considerations aiming at obtaining the Laplace transfer function model of an uncoated {front surface electrode is a thin layer of metal) pyroelectric detector are presented. The pyroelectric detector model was implemented in MATLAB-Simulink environment for simulation studies. The exemplary simulation was performed for the prototype of a polyvinylidene fluoride (PVDF) pyroelectric detector designed and constructed by the authors. Construction, physical parameters and some results of the experimental studies performed with this detector are presented, among others, in [3,4]. Exemplary results of less known simulations illustrating the influence of such parameters as the thermal time constant on the detector voltage rcsponsivity are given. The possibility of simulation study on a basis of time dependences of the voltage pyroelectric response to modulated radiation with different shapes is indicated. The simulation results show that the voltage responsivity of the pyroelectric detector exposed to rectangular modulated radiation of low frequency is higher than that to sinusoidal and trapezoidal modulated radiation. This type of simulation investigations gives important information about the properties of the pyroelectric detector in such applications as remote temperature measurements, monitoring of radiation power or thermovision measurements.
