Abstract

This paper describes a numerical filter for removing noise from thermoelastically measured isopachic information. The filter is based on the isotropic compatibility equation and uses a least squares fit to a general solution of Laplace's equation. The fact that relevant mechanics of the measured data are incorporated into the filtering algorithm causes the filtered data to converge to a quality solution. The technique is demonstrated with illustrative examples, including the use of measured input information.
