Abstract

This work presents the theoretical analysis of the effects of dielectric relaxation on the response of polymer piezoelectric sensors. In systems that obtain spatial information from temporal signals, such as optoacoustic tomography, the accurate characterization of transducers is very important. There are many works in the literature about reconstruction algorithms assuming ideal piezoelectric sensors. However, the distortions introduced by polymeric broadband ultrasonic sensors have been less treated. In consequence, a model is necessary to assess the relative importance of these effects in comparison to other factors that limit the resolution of the image.
