Today’s night vision technology allows individuals to operate under the cover of complete darkness. This comes in handy for law enforcement and the military when they need to perform missions and can’t risk it during the daytime hours. Night vision technology relies on both image intensifiers and thermal imaging.
Night vision technology that utilizes thermal-based systems uses the upper levels of the infrared light spectrum, one that’s not able to be detected by the human eye. Because hot objects emit more infrared light than cold ones, infrared sensors scan the area and focus on those items that are putting out more heat. The data collected on the infrared radiation is analyzed and presented in the viewfinder. Because thermal-based technologies don’t rely on any light emissions they can detect and transmit images in areas of total darkness.
In areas where there is minimal light, the use of an image intensifier will amplify the available light and transmit it. This technology helps to make dark environments visible in areas where the naked eye might not be able to detect the differences in the environment.
Surveillance operations that require the cover of darkness to be completed benefit from the use of night vision technologies. Night vision can be used with binoculars, video cameras, still cameras and telescopes. The most popular and easily recognizable use of night vision technology is in night vision goggles. These goggles provide the user with real-time images, allowing them to move around and function in complete dark environments.
