How can night vision goggles operate? The target lens with the goggle gathers available photons. These are converted into electrons in the picture intensifier tube. The electrons are multiplied, normally amplified, and exhibited on phosphor (white or green) on the backend on the tube, causing the image the thing is. https://goggles-with-night-vision57902.yomoblog.com/34360150/an-unbiased-view-of-night-vision-goggles
