Infrared technology Q & A
First, why can not be measured by infrared to the precise temperature of objects?
The vast majority of objects are not bold, that emissivity ε ≠ 1, so we measured radiation not only the temperature of objects, but also with the launch of the relevant rate. In addition, the object emits radiation detectors in the process of arrival, as well as losses caused by various factors. As a result, temperature measurement equipment received radiation is not only a decision by the objects of the radiant energy radiation temperature. Therefore, the measured temperature is not the true surface temperature, are just some of the apparent temperature, even after the amendment, and the true surface temperature T between some differences still exist.
Second, the advantages of infrared imaging technology?
The use of thermal imaging technology to this invisible "hot like" into a visible image, so that test the effect of intuitive, high sensitivity, the equipment can detect subtle changes in thermal state, accurately reflect the equipment internal and external situation of the fever, high reliability of equipment problems found very effective. Using infrared condition monitoring and diagnostics technology has long-range, non-contact, no sampling, non-disintegration, but also has an accurate, fast and intuitive features, real-time online monitoring and diagnosis of the majority of electrical equipment failure (almost cover all the electrical equipment fault detection). It has been of great importance to the power industry at home and abroad (outside the universal application of the late 70s of an advanced condition-based maintenance system), and rapid development. Infrared detection technology, electrical equipment to improve the reliability and effectiveness, improve the operation of economic efficiency, lower maintenance costs are very important significance.

Third, what is the night-vision technology?
With night-vision technology is the realization of optoelectronic imaging device at night to observe a photovoltaic technology. Dim light of night-vision technology, including night vision and infrared night vision in two ways.
(A) night-vision technology, also known as low-light-level image intensifier technology, through the image intensifier tubes with night-vision goggles, the night sky (including the Moon, Stars and atmospheric glow) to illuminate the target as to strengthen the weak, for observation photo imaging technology. Its equipment as follows: dim light of night vision.
Disadvantages: single observation, limited-horizon, observers must be coordinated equipment in person at the scene, goal-oriented, such as direct observation.
(B) infrared night vision technology is divided into Active Infrared night-vision technology and passive infrared night vision technology:
1). Active infrared night vision technology is exposed through the initiative and make use of the target infrared reflection of infrared light source to implement the observation of night-vision technology, corresponding to active infrared night vision equipment.
2). Passive infra-red night vision technology is the goal of their own through the launch of the infrared radiation to achieve the observation of infrared technology, which according to the goals and objectives of the various parts of the background or the temperature difference between the thermal radiation or worse to find the target. Its equipment for the thermal imager. Thermal imager with night vision is different from other unique advantages, such as in fog, rain, snow weather work, the role of distance and to identify camouflage and anti-jamming, etc. (all passive, all-weather) has become a foreign night-vision The emphasis on the development of equipment and will be replaced to some extent, low-light-level night vision.
