First thermographic camera In 1929, Hungarian physicist KÃ¡lmÃ¡n Tihanyi invented the infrared-sensitive (night vision) electronic television camera for anti-aircraft defense in Britain. The first thermographic cameras developed were infrared line scanners.
In the year 1800, Sir William Herschel discovered the existence of infrared by performing an experiment very similar to the one we show here.Herschel passed sunlight through a prism. As sunlight passes through the prism, the prism divides it into a rainbow of colors called a spectrum.n the year 1800, Sir William Herschel discovered the existence of infrared by performing an experiment very similar to the one we show here.
