#PAR Block Size for 1.27
Greg,
Once you adjust for the backround thermal radiation, a human body shows its
relative hot and cold areas defined simply by luminescence: the dark areas are
colder than the light areas (or the opposite if you hit the reverse button).
The face shows the hottest areas along the hairline (my wife has bangs) and the
colder areas are the sinus regions adjoining the nose and under the eyes with
the tip of the nose being the coldest. The hands show that the fingertips are
the coolest.
My daugther had a friend over and I went out of the room and told them to place
a finger on one of the wooden Marimba keys and then I came in with the viewer
and quickly found the one key with a "hot" spot. Then they had me touch a key
and they'd find it. Boy, I'd like to keep this thing!
I'm a scientific/investigative consultant to a new Learning Channel TV series
and they sent me the unit because they have some video tape from a group of
"scientific" supernatural investigators who claim to see ghosts with the
Thermal viewer. I can easily duplicate their "ghost" images and they're coming
to videotape me on Thursday demonstrating how it can be done.
