Abstract

In these resolution studies, a sophisticated version of the finite element method was used to model the time evolution of a laser pulse within a simulated medium. An array of 'detectors', placed in the medium, were used to measure the pulse intensity at a discrete set of points. As we will show in this report, the 'detectors' were able to resolve distortions in the pulse owing to two 1 mm diameter inclusions embedded in this otherwise homogeneous medium and separated by as little as 1 mm. Thus, the data from these detectors could, in principle, be employed by an algorithm designed to solve the inverse problem: the imaging, at 1 mm resolution, of inclusions based upon data from detectors placed, or surrounding, the medium.
