Abstract
The Laser Intensity Modulation Method (LIMM) has recently been extended to the study of thin-film ferroelectrics on a substrate. The analysis of the experimental data requires the numerical solution of a Fredholm integral equation of the 1st kind, an ill-posed problem having multiple solutions. The techniques that have been applied previously for thick film analyses are not useable in this case because of the interference of the top electrode. A series solution method has been developed to solve this problem. The polarization distributions can be computed as 8th-degree polynomials by use of the constrained regularization method and singular value decomposition.
