Para experimentor - About a year ago I got interested in Infrared and how it could be used as a way to make the invisible visible. I was simply trying to make an IR night scope nothing more. What I got was something unexpected instead.
I first experimented with a zero lux camera using 900 nano-meter IR LEDs for illumination. That worked fine but I was not getting the outside viewing distance that I so badly desired. I began experimenting with high intensity IR illumination until I came to the perfect light(a 200,000 candle power flood light) this gave me excellent long distance viewing outside.
My first experiments resulted in me being able to see ORBS inside and outside my house they could be seen moving slowly a few inches above the floor then vanishing, moving up toward the ceiling then vanishing, moving down from the ceiling then vanishing.
One night while watching a "group" of these outside last winter (23 degrees F), one flew toward me zig zagged left, right, left vanishing off my left shoulder. But then when I started working with 200k CP IR illuminator I began to notice that the ORBS were getting less and less. I began realizing that the intense light might be "scaring away", "driving away"; or what ever word you might want to use but the bottom line is the intense light sent the ORBS away. But why I pondered then it came to me to you and I IR is invisible but perhapes to ORBS that frequency of light(IR) may be very visible and if one uses 200k CP IR that may be extremly irritating to them maybe like looking at the sun to you or I any thoughts on this !!!????
