<br> Infrared camera for development can be divided into three phases, the first stage is mankind through the manufacturing tools, extended physical activity; the second phase through the judgment, seeking more clarity and a broader understanding and judgement criteria; whereas humans in recent .years to strengthen the capacity of access to information, expanded the scope or adds a new feeling of the senses, so that our brains can receive more information, it is the human development of the third stage. <br> In this phase, the development .of infrared technology has been the human senses increase from five to six. During the Gulf war, high-tech weapon demonstrates advanced technology platform, become the world's scientific and technological development of the wind direction, has become the world compete for research and development direction .and focus. These high-tech technology has become the new industry and investment hotspots, and create millions of wealth and unpredictable social benefits. In these new technologies, satellite positioning (GPS) and infrared thermography (TIS) two technologies. Satellite positioning system ( .GPS) has been very widely used in various industries, from military to civilian has broad development prospects of the industry, its application development speed, far more than people had expected, for example: in the widely used car alarm system, etc. <br .> Infrared thermal imaging technologies, is also a very bright future for high technology, its extensive application will cause many innovative changes in the industry. <br> I. What is infrared thermal imaging? <br> Ray is familiar. What are the rays .of light is visible, is the human eye can feel of electromagnetic waves. The wavelength of visible light: 0.38 - 0.78 micron. 0.38 Micron short wave and long wave 0.78 Micron, the human eye can feel. 0.38 Micron short wave is located in the .visible light spectrum, known as UV purple than 0.78 Micron long wave is located in the visible light spectrum red, called infrared. Infrared, also known as infrared radiation, which is the wavelength of 0.78 ~ 1000 microns of electromagnetic waves. Which wavelength 0.78 ~ .2.0 Micron part known as the near-infrared, wavelength 2.0 ~ 1000 μm thermal infrared part is called. Camera imaging get photos, TV camera get TV images are visible light Imaging. All objects in nature, and can radiate infrared, so use detector determination .target itself and the difference between the background and can be infrared different infrared images, the formation of thermal infrared thermal image image is called. Goals and objectives of the thermal image visible images, it is not a human eye can see target visible image, but .a destination surface temperature distribution of images, changing a Word, infrared thermal imaging to the human eye cannot see the target surface temperature distribution, into the human eye can see represents the destination surface temperature distribution in thermal images. <br> II. infrared thermal .imaging features? <br> There are famous United States IR scholars say: "mankind's development can be divided into three stages. The first stage is mankind through manufacturing tools, extended physical activity during the second phase of capacity, by increasing the judgment, seeking .more clarity and a broader understanding and judgement criteria, and in recent years to strengthen the capacity of access to information, expanded the scope or adds a new feeling of the senses, so that our brains can receive more information, it is the human development of .the third stage. In this phase, the development of infrared technology has been the human senses increase from five to six ". This goes, I think it's just right for the infrared imaging technology in contemporary importance. Because our surrounding objects only when their temperatures .up to 1000 ° c and above, will be able to make visible. By contrast, all temperature around us in absolute zero (-273 ° c) above, will not stop issuing thermal infrared. For example, we can calculate that a normal person's .thermal infrared energy, approximately 100 Watts. Therefore, thermal infrared (or thermal) is the most widely used exist in the nature of the radiation. The universality of thermal radiation in addition, there are two other important characteristics. <br> 1. air ., smoke, and other visible and near infrared absorption, but for 3 ~ 5 microns and 8 ~ 14 μm thermal infrared is transparent. Therefore, the two-band known as the "thermal infrared atmospheric window". Use of these two Windows, you .can make it in the full light of the night, or in the cloud clouded battlefield, clearly observed in the front. It is because of this characteristic, thermal infrared imaging technology military provides advanced night vision equipment for aircraft, ships and tanks fitted with a .forward-looking system 24 / 7. These systems during the Gulf war played a very important role. <br> 2. object of the size of the radiation energy, direct and surface temperature. Radiation characteristics of this so that people can use it to .make the objects without contact temperature measurement and thermal analysis, thus contributing to the industrial production, energy conservation, the protection of the environment and so on provides an important means of detection and diagnostic tools. <br>.
