Night Vision Equipment

I have a question about Night Vision Equipment. I know Night vision works by sending out an invisible beam and enhancing that beam. What happens if more then one person is using NV equipment at the same time and in the same area?

I am asking because of a ghost hunting show that was on. In the show several people were using NV equipment and they recorded shadows that looked like people. The shadows appeared in front of near by trees and basically in front of the cameras. Specifically I saw 3 people with goggles, 2 cameras and one thermal camera that also had night vision.

To me this shows that the people using NV behind the camera man were casting beams from several angles that caused shadows from the people around. The show claims that these are shadows of ghost children.

I am posting here because my main question is about night vision equipment; and I want answers about the equipment not about the existence of ghosts.

I was active Army for 6 years and have a good bit of experience with a few NVG models. As to what they were using i cant answer you, but most NVG systems take in infrared light and magnify it so you can see. the device usually has the ability to project a narrow “spot” of IR light if its a moonless night and so on.
Older model NVG devices can produce some interesting things. I was using an old starlight model because my 14’s got broken getting out of a CH-47. Thank god I only had to use them for a few days. The starlight has no grain (fuzz like an old TV) adjustment and looking through them for long periods of time in certain terrain features can produce some “ghosting” effect which is a trick of the ambient light and shadow through the magnification and filtering portion of the device.
All that being said most newer gen 4 or 5 devices have overcome these faults. ps-unless its pitch black (no ambient light) using you IR illuminator A.) makes no sense B.) makes you stand out to anyone else with NVG’s and can interfere with the filters on your buddy’s system, i.e.- overload if you look him in the face while his are turned on.

The Navigator is an economic thermal imager. It provides crisp, clear thermal imagery in total darkness and light fog or smoke. It features the same thermal imaging technology found in many of FLIR’s most sophisticated maritime systems, but is packaged for users who have navigation as their primary application. Unlike other night vision systems that require low amounts of light to generate an image, the Navigator needs no light at all.

Our cat goes crazzy in the middle of the night, shot in complete darkness using Sony HVL - IRH2 infared light. A black cat at night becomes totally visible under infared light, without the IR light I couln’t see him when he was a couple of feet away.

Our cat was attacking the handy-cam camcorder lens cap in darkness as I was filming him in infrared. Cats are ruthless hunters and this kitten playfully attacking the lenscap is preparing for the time when he will bring death to mice in the middle of the night.
