Study on the Applicability of Passive Millimeter Wave Imaging Technology in Real Fire

Abstract

In the scene of the fire, fire fighting and rescue troubled firefighters quickly the main impediment to rescue trapped personnel is high fever of smoke and fire, existing hand-held infrared imaging devices are usually used to monitor the combustion temperature, to search for hidden fire action such as content, cannot penetrate smoke fire, fire inside the high temperature environment will also be harmful to its imaging effect. This paper design a paragraph 1 to fire for fire fighting and rescue typical application background of passive millimeter wave imaging, analysis of fire under the condition of the realization of the millimeter wave imaging technology means and interference factors, verification of millimeter wave smoke fire environment through typical performance, break through the limitations of the existing fire imaging technology, make up for the inadequacy of infrared imaging devices, can effectively improve the efficiency of reconnaissance, shorten the rescue time and improve the security of firefighters and trapped personnel.

Millimeter-Wave Single-Pixel Imaging Using Electrically-Switchable Liquid-Crystal Mask

“…Millimeter-wave (MMW) imaging technology is used in various practical applications, such as nondestructive inspections [1], material analysis [2], security surveillance [3], disaster rescue operations [4], and remote sensing [5]. MMW penetrates into ordinary dielectrics, including plastics, papers, and clothes [6], and conductors such as metals greatly reflect MMW.…”

“…Hence, MMW is useful for detecting the moisture in grains [14], fruits [15], wood [16], and pharmaceuticals [17]. In addition, MMW is transparent to smoke and flames [4], [18], [19], that is, MMW inspections can determine lives during disaster rescue operations.…”
