Infrared diagnostic techniques

2014-08-03

Infrared imaging is the use of infrared detectors, optical imaging lens, and optical scanning system (advanced focal plane technology eliminates the need for ray machine scanning system) to accept the measured target of infrared radiation energy distribution graphs reflect the infrared detector photosensitive between the optical system and infrared detector in the $ on a ray machine scanning mechanism (focal plane thermal imager is no such institutions) of the measured object infrared thermal image scanning, and focus on the unit or on the spectrophotometric detector from the detector to convert infrared radiation into electrical signals, amplification processing, conversion or standard video signal through the TV screen or monitor display infrared thermography. The thermal image map and surface heat distribution field corresponds to; is essentially part of the infrared radiation of the object under test, thermal imaging maps the signal is very weak, compared with the visible image, the lack of level and three-dimensional, so The measured target more effectively determine the actual course of action for infrared thermal distribution field, often using a number of auxiliary measures to increase the practical function of the instrument, such as image brightness, contrast control, in fact, standard calibration, pseudo-color depicting technology.
Infrared diagnostic techniques is through to absorb this infrared radiation energy to measure the temperature and the temperature field distribution of the device surface, in order to determine the equipment fevers.
Infrared detection technology is a key promotion project for the Ninth Five-Year National Science and Technology, infrared detection is an on-line monitoring of uninterruptible power high-tech detection technology, which combines optical imaging technology, computer technology, image processing technology in the one issued by the receiver object the infrared radiation, infrared, thermal image is displayed on the screen, in order to accurately determine the surface temperature distribution, with accurate, real-time, fast, etc.. Objects of any kind due to the movement of its own molecule, kept out radiation infrared heat, which formed in the surface temperature field, commonly known as "thermal imaging". Infrared diagnostic techniques is through to absorb this infrared radiation energy to measure the temperature and the temperature field distribution of the device surface, in order to determine the equipment fevers. Infrared attending the test equipment, such as infrared thermometers, infrared television, infrared imaging, and so on. Like infrared thermal television, infrared imaging devices such as the use of thermal imaging technology to this kind of invisible "thermal image into a visible image, to test the effect of visual, high sensitivity, can detect subtle equipment thermal state changes accurately reflect the equipment, internal, external heat, high reliability and the discovery of the hidden equipment is very effective.
