Numerical prediction of the piezoelectric transducer response in the acoustic nearfield using a one-dimensional electromechanical finite difference approach
O. Melchert, E. Blumenröther, M. Wollweber +1
We present a simple electromechanical finite difference model to study the response of a piezoelectric polyvinylidenflourid (PVDF) transducer to optoacoustic (OA) pressure waves in…

Detection and numerical simulation of optoacoustic near- and farfield signals observed in PVA hydrogel phantoms
O. Melchert, E. Blumenröther, M. Wollweber +1
We present numerical simulations for modelling optoacoustic (OA) signals observed in PVA hydrogel tissue phantoms. We review the computational approach to model the underlying mech…

Optoacoustic inversion via Volterra kernel reconstruction
O. Melchert, M. Wollweber, B. Roth
In this letter we address the numeric inversion of optoacoustic signals to initial stress profiles. Therefore we put under scrutiny the optoacoustic kernel reconstruction problem i…
