Simulations and Experimental Data

Here we show some simulations and experimental data. All examples have been calculated for a poled 12-micrometer PVDF film (24 microns for the bimorph).

The upper plot shows the pyroelectric current for a uniformly poled sample with edge depolarization on both sides. The bottom figure shows the original depth profile of the pyroelectric coefficient (black trace), as well as the distribution reconstructed from the pyroelectric signal using the reconstruction and approximation methods. For this type of distribution, both methods produce satisfactory results.
