There is nothing mysterious about it, as it is based on scientific principles involving light and its interactions.

Hi Adele,
Is this discussion still available somewhere? I would like to read it because offhand I would think that there is a difference between using light reflected off a metal surface to determine something about the composition of that surface, and using light reflected off a 2D photographic representation of an object to determine something about the composition of the represented object (not the composition of the photograph itself). I am (earnestly) seeking enlightenment (if you pardon the pun) here ...
Thanks!
Hi, Albert,
That discussion was on the Education Forum some years ago. I don't know if this is available anywhere, unless the Ed Forum was archived. The term "photonics" or "photoptics" (as best as I can recall, probably "photonics") was used to describe Wilson's method. Hope this helps. Try Google for definition.
Sorry to be late in replying, but I am not at my own computer these days.

P.S. Albert, the correct term is PHOTONICS for Tom Wilson's works. Photoptics refers to the optics involved in vision of the eyes. Photonics involves all forms of electromagetic radiarion, which includes light, and this is a special branch of physics. Google can supply definitions of photonics and examples of this science.
Hi Adele,
Possibly this is the item on the Ed Forum you are talking about.

Thanks, Adele, and Ray. I'll give it a look.
