Night Vision
Covert operations and movies that highlight nighttime surveillance operations typically feature night vision technologies and night vision goggles or binoculars. Looking through night vision goggles provides the viewer the ability to see in the dark and the world is viewed in a green light when using these goggles.
How is it that you can see in complete darkness when wearing these devices? There are two different technologies used: thermal imaging and image enhancement. Thermal imaging captures the heat of objects in the area and then projects that as an image. Image enhancement captures whatever small amount of light (even if it’s not visible to the naked eye) and amplifies it to allow you to see the surrounding area. Visible and infrared lights are captured with image enhancement and then sent to an intensifier so the human eye can discern what, or who, is in the area. The light energy that is captured is converted into electrons, passed through a fiber optic technology inspired plate then projected onto a phosphorous screen on the lens of the night vision unit. All of this happens in less than the blink of an eye so the individual wearing the goggles sees it in real time.
As with all technologies, night vision and the ability to capture images in near-dark and dark conditions continue to improve.
