Night-vision device [SEP] History
A retrospective classification of NVDs into "generations" was initially introduced by US manufacturers, through the US government. Under this periodization, the period prior to the end of World War II has sometimes been described as "Generation 0". In 1929, Hungarian physicist Kálmán Tihanyi invented an infrared-sensitive electronic television camera for anti-aircraft defense in the UK. The first military night-vision devices were introduced by the German Army as early as 1939 and were used in World War II. AEG started developing the first devices in 1935. In mid-1943, the German Army began the first tests with infrared night-vision () devices and telescopic rangefinders mounted on Panther tanks.
