This paper introduces the Maximum Entropy (ME) method of resolving underdetermined objects (flaws or inclusions) by a physicists' brand of non-linear processing of the image data. We survey three areas of research: synthetic aperture imaging to resolve three dimensional flaws, with the aid of selective back projection; scattering from anomalies according to the inhomogeneous Fredholm integral equation of the second kind; and ultrasonic flaw characterization by the boundary integral equation method. A simple example is offered to illustrate the potential resolving power of the ME method for problems in the second area. Some criteria for effective ME inversion are presented.
