Description
Technical field
It is used for the device that the scene of a fire is searched and rescued based on optical fiber infrared holography the present invention relates to a kind of, belongs to optical fiber infrared holographic applications
Field.
Background technique
Fire is one of the common disaster for threatening people's security of the lives and property, how fast in scene of fire for fire fighter
Fast effectively find is undoubtedly a critically important problem to rescue personnel positioned at what flame or smog were blocked below.Although disappearing
Anti- equipment is increasingly advanced, but at present for scene of fire fire fighter how to be quickly found out by flame or smog block to
This problem of rescue personnel is also a lack of substantive solution.
Traditional holographic technique has graduallyd mature in terms of real time imagery, is applied to various measurements, imaging etc., due to passing
The holographic laser light source used of system is generally visible light wave range, is affected by flame or smog, so cannot be used directly for fire
Calamity scene search and rescue by smog block to rescue personnel；Infrared thermal imager is used for fire fighter's fire as existing equipment
Field rescue by smog block to rescue personnel, its advantage is that can through smog see behind smog the case where, be well suited for
For fire fighter scene of fire search by smog besiege to rescue personnel, disadvantage be exactly face it is fiery to rescue personnel
The case where flame besieging is blocked can not see that flame is subsequent to rescue personnel and situation, when fireman can not when the scene of a fire uses
See the case where rear is covered by flame, how to solve in scene of fire to the imaging problem to rescue personnel blocked by smog
Just seem very urgent and important.
With constantly improve for infrared laser, the laser light source of holographic technique gradually expands to from visible light wave range infrared
Wave band, and the research and development of the optical fiber with infrared band have developed completely new optical fiber infrared holographic technique.
