How do night vision goggles and thermal-imaging devices work differently from regular binoculars or?

Binoculars are simply two telescopes side by side, one for each eye. But there's a catch. When light rays from a distant object pass through a convex lens, they cross over. That's why distant things sometimes look upside down if you look at them through a magnifying glass.Apr 7, 2016

Thermal imaging cameras, also called infrared cameras, detect the heat given off by an object or person. Thermal imaging cameras have lenses, just like visible light cameras. But in this case the lens focuses waves from the infrared energy present in all objects onto an infrared sensor array.

Night vision goggles using image enhancement technology collect all the available light, including infrared light, and amplify it so that you can easily see what's going on in the dark. The other way uses a technology called thermal imaging.

There are two basic principles for any night vision device. One is to use a huge lens, like several inches wide, to collect a lot of light and focus it into a small area. The other is to use a tv camera to process the image and a little monitor to make it visible. Both might be used together.
