Typical individual combat scenarios were presented, which include battlefield observation, reconnaissance and surveillance, target positioning and laser designating, light weapon precise shooting, sniper warfare, fighting with targets hidden in trenches, parachuting and airlanding at night, night fighting, entering indoor or dark underground space from the bright environment, observing/searching/shooting in the low-visibility environment. To meet these battle requirements, individual soldier night vision goggles have been developed to integrate with visible light scope, laser rangefinder, satellite positioning system, digital compass, communication and other functional modules. Therefore, night vision goggles possess more complex and accurate combat capabilities, such as night vision imaging, range finding, positioning, calculating, information fusion, fire control computing and wireless transmission.
