The night vision goggle is a device used for viewing the surrounding region during night. This goggle works effectively on a cloudy moonless night and with this goggle, one can view their surrounding area clearly. The working of night vision goggle purely depends on the technology used within the goggle.
There are two types of technologies used by the goggles for night vision; one is image enhancement and the other is thermal imaging. The image enhancement technique collects all the available light within the given region and enhances them effectively. The thermal imaging technique uses IR sensor for viewing the images. With these technologies, night vision goggles are operated effectively at night.
