Introduction: 

Traditional scanners can be only fixed in a special position, opening a 90 degree hole in right front of the target range  - measuring the infrared temperature distribution of a line, and use its own movement or rotation to get the surface imaging, but the application with a certain limitation. if users want to get large rest object or space temperature field analysis, such as within a few miles of forest fire prevention, wharf of dangerous goods and the monitoring of spontaneous combustion. Under this condition, the traditional scanners will useless, if use focal plane thermal imager, a few companies also need to be more than 10 sets For this kind of application, our company has developed a two-dimensional scanning thermal imaging system, which can monitor the complete fire control and alarm within 4km distance.
