Infrared radiation has been studied with detectors of one kind or another since about 1800. The difference between the techniques of the first century-and-a-half and the period since World War II is that the earlier devices were thermal detectors, responding to temperature change caused by integrated absorption of energy, while the more recent devices ...

Abstract In 1608 the Nether landish eyeglass maker Hans Lippershey put two lenses together and invented the telescope. He intended it as an in strument of war, for spying out the enemy. The Estates of Holland, in the midst of the Eighty Years’ War of independence from Spain, awarded him a substantial sum.
