Synopsis:

Military applications of optical technology have a long history. For over 300 years, telescopes and binoculars have extended the range of a commander's vision. Periscopes allow submariners to view surface activities while submerged and, during World War II, the Norden bombsight provided American bombardiers accuracy that, although crude by today's standards, was unparalleled for its time. Since the invention of the laser in 1960 and the light emitting diode in 1965, advances in electronics have spilled over into optics and brought opto-electronics to the battlefield. Shortly after its invention, the laser was used to guide munitions in Vietnam. Night vision technology also made its first battlefield appearance in Vietnam. More sophisticated infrared imaging gave coalition forces in Operation Desert Storm a critical advantage in night operations.
