of industrial real-time imaging system, and after improving, full function infrared imager launched in 1988, the temperature measurement, modification, analysis, image acquisition and storage in one, the function of the instrument, precision and reliability are improved significantly.

With the development of society and economy,

This military reconnaissance equipment has also been transformed into a rescue instrument 一infrared life detector.

At present, the technology of infrared life detector is relatively mature, the price is relatively low, good performance to price ratio, it is generally equipped with emergency rescue departments in various countries, widely used. With the rapid development of image conversion technology and computer technology, infrared life detector will inevitably have greater improvement in imaging, positioning and other aspects.

The audio life detector application audio sound waves (including shock wave) of the basic principle, it uses advanced high-tech microelectronic processors and sensitive sensors, special electronic device will spread to other non target noise background interference wave filtering, the life is most needed to ensure the target signal uptake, quickly identify the location of trapped persons・After years of practical experience and continuous development, audio life detector has been developed to the fourth generation products・ There are more than 10 fire rescue personnel in the United States, Britain, France, Japan, Singapore, Israel, who are using audio life detectors to find trapped lives・ As the audio life detector is a passive instrument to receive audio waves, it also has some limitations, such as easy to be
