This concludes my tutorial.

I invite the audience to review my slide show and speaker notes, which are available on the WEB at the address shown here.

I also have with me some reprints of a recent publication in the optometric literature which contains additional tutorial material as well as some clinical examples of the use of the technique.

Lastly, don't forget that Vengu is organizing a feature issue of Trends in Optics and Photonics which will also contain a number of tutorial papers as well as current research reports in the general area of visual optics.
