Infrared thermal imaging technology is a passive, non-contact detection and identification technology, can use the target and the background or between the target parts of the temperature difference or radiation differences in the formation of infrared radiation characteristics of the image to find and identify the target, its two basic functions are temperature measurement and night vision.
Thermal imaging camera works on the principle of thermal infrared imaging technology. Modern thermal imaging devices work in the mid-infrared region (wavelength 3 ~ 5um) or far-infrared region (wavelength 8 ~ 12um). By detecting the infrared radiation emitted by an object, the thermal imager produces a real-time image, thus providing a kind of thermal image of the scene. Its core is a thermal imaging camera, which is a sensor capable of detecting very small temperature differences, the temperature difference into a real-time video image display. But only see the thermal corridor of people and objects, can not see the real face of the object. Advantages 1, day and night can be used normally 2, extreme weather can be used 3, can see through the fog, rain, smoke and other obstacles 4, all heat-generating objects are nowhere to hide in nature as long as the object above absolute zero (-273 ℃), will be constantly outward radiation of infrared. Thermal imaging that is through the optical system, infrared detector chip and electronic processing system, the object surface infrared radiation into a visible image. Simply put, the principle of thermal imaging is to use temperature imaging to transform the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.
Thermal imaging is not affected by visible light, can be 24 hours clear imaging, non-contact temperature measurement, through the smoke and fog and other advantages, can be applied to human temperature measurement, industrial temperature measurement, automatic driving, security fire, outdoor observation, etc.. Commonly speaking, thermal imaging camera is the invisible infrared energy emitted by the object into a visible thermal image. The different colors on the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heat generation of the target can be studied to provide a basis for work and research. For example, the infrared thermal imaging camera can check the floor heating leakage, can accurately detect the indoor pipe network, such as the distribution and direction of the location of the floor heating pipes, water pipes, hot water pipes, and can accurately locate the location of pipe leakage. Underfloor heating leaks often exist in two phenomena.
1. fuzzy diffusion of pipes at the leaky location, the storage of non-linear, presenting a cloud of heat in the infrared picture.
2, the leak location temperature is high, in the infrared picture presents a white bright color.
The main performance indicators of thermal imaging night vision device classification.
1. resolution: resolution is the assortment of thermal imaging night vision device is an important indicator, night vision device affects the cost of thermal imaging night vision device one of the keys. General thermal imaging night vision camera resolution of 160x120, 336x256 and 640x480 three. The selling price from tens of thousands to hundreds of thousands of dollars.
2. the resolution of the built-in screen: we observe the target through the thermal imaging night vision device, in essence, is to observe its internal LCD screen. The top thermal imaging night vision device, its built-in screen resolution and clarity are very high, so that it is clearer observation effect and better vision.
3. magnification: due to the technical bottleneck, the physical magnification of the thermal imaging night vision device, at present, the largest magnification can be produced for 5 times.
4. double tube or single tube: double tube in the use of comfort and observation effect are obviously far better than single tube, of course, the price of double tube thermal imaging night vision device will be much higher than the single tube thermal imaging night vision device, double tube thermal imaging night vision device in the production technology will be much higher than the single tube.
