W discovered infrared now, time passed till now, the progress of the infrared technology to todays course for nearly two hundred years. Then, the infrared radiation and infrared receiver, test components and various infrared receiver, study is also testing parts, but progress is slow, around until the 1940 s was a real modern infrared technology. At that time, PBS material and several kinds of infrared transmission is studied, but make the material into the military infrared system, such as anti-aircraft gun guide apparatus, instruments used for reconnaissance, ship to detect instrument and used to track system, and so on. Of these, some too small to produce, but which are not actually used. Later, the United States, Britain, the former Soviet union and other advanced countries are developing the technology. Especially the emerging powers - the United States, in it and focus on the infrared technology in military application. Curiously, though, infrared sensors in the world, some developing countries more than Europe and the United States and other developed countries more bullish on the prospect of it. While Europe and the United States there are so many industrial countries to join in, but its market gradually saturated; China, however, and some emerging countries and regions such as Latin America, with the progress of their economic recovery and rapid, many countries and places are also strengthen the development of industrialization, the
