Kirchhoff Imaging
Kirchhoff Imaging
This Demonstration shows some simple cases of Kirchhoff imaging. A locatable point diffractor (red) is introduced as the perturbation to an otherwise homogeneous 2D medium, and a locatable point source (blue) is used for illumination. The result of the illumination is recorded at detectors placed along the edges of the square medium; their number per side and how many sides they are placed on is controllable by setters. Check the "image" box when ready to calculate. Uncheck to change the problem geometry.
