AB: At present there is no formal theory for nonlinear appraisal analysis. A lthough this makes the problem difficult but there are number of methods proposed in the past such as linearized analysis (Backus and Gilbert, 1 970), funnel function approach (Oldenburg, 1983) and nonlinear Backus-Gi lbert theory (Snieder, 1990) have provided direction to look at this pro blem. In this paper I will briefly review these methods and discuss some new developments in the nonlinear and linearized point spread function analysis as a model const ruction problem. Point spread functions (PSF) describes how an impulse f unction in the model is observed in the inversion result. Knowledge of P SF provides insight into the inverse operator. It allows to carry out image interpretation such as regions of the model supported by data and provides the ability to design focused surveys.Examples from seismic tomography and controlled source EM will be presented.
