Abstract
In this paper the basic principles of LCSI are briefly described. Furthermore, we investigate the interference signal coming from a semitransparent, multilayer object theoretically and experimentally. The interference signal is modelled using a one-dimensional transmission line approach. The theory for this model is well known from the exact matrix theory of multilayered systems. We have extended the model for phase investigations and simulated the effect of a delamination when measuring through a semitransparent layer. The model is verified by experimental results from LCSI measurements.
