I think your talking about Kirlian photography. Here is something verbatim from a web page that deals with it. http://www.synergy-co.com/kirlian.html#equipment Equipment Used to Produce Kirlian Images Kirlian photographs are created utilizing a metal plate, and a generator or oscillator to produce a high voltage field of variable pulse and frequency. There is no light used in this process. Through the action of high frequency fields, electrons are emitted from the body of an organism and this energy is dissipated into a photographic emulsion, as light would be. Different colors or shadings appear in a brilliant corona surrounding the object, depending upon the type of film used. I think the light source is Cherenkov radiation which I understand to be photons emitted when electrons move to lower energy orbits. Presumably the applied high frequency field energizes the atoms and moves the electrons to higher energy states?
That might be an interesting way to find points for ESD testing? Perhaps it shows where the field tends to concentrate. The Kirlian pictures are always seem to have pointy fields. Well, that's at least 2 cents. -George -----Original Message----- From: geor...@lexmark.com [mailto:geor...@lexmark.com] Sent: Thursday, August 09, 2001 1:00 PM To: emc-p...@ieee.org Subject: board scanning on the cheap (sort of) Well, this discussion has reached the point where I must add something I read about some years ago. It goes something like this: For many years, Russia was known to conduct many experiments involving paranormal activity, probably to determine if there were any military value in such phenomena as psychic communications etc., if in fact they existed. I was surprised to see an article in a National Geographic years ago that told of one such experiment. It involved photography of the "aura" (presumably electromagnetic fields) that surround the human body. The peaks in this aura, or field were found to be consistent with the primary acupuncture points long before identified by the Chinese. A "faith" (hand-on) healing was photographed, revealing that the aura of the healer diminished during the process while the aura of the person being "healed" increased, i.e. a possible transfer of energy. The point of all this is if the Russians truly developed a means to photograph the low power EMF surrounding humans, it would seem that the same technique would also photograph the EMF surrounding PCBs etc. I have no comment on whether any of the above is true science, but I DID read it in the generally respected National Geographic, albeit not a scientific journal.
