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 1984, a major milestone occurred for infrared thermometers. IRT applications were soon found in the hospital, home, and ear! One of the turning point applications - the infrared ear thermometer - resulted in the sale of six million pieces, and consequently a substantial drop in the IRT's sensor cost. This remarkable invention (USP4602642), has continued to evolve, and continues to thrive in the market today.
