Fire scene searching and rescuing device based on infrared holographic technology

Abstract

The invention discloses a fire scene searching and rescuing device based on an infrared holographic technology, used for searching to-be-rescued personnel blocked by smoke or flame by firefighters ona fire scene and belonging to the field of infrared holographic application. The fire scene searching and rescuing device comprises an infrared laser, a beam splitter I, a light-tight shell, a beam expander I, a beam expander II, a lens I, a lens II, a beam expander II, an IRFPA (infrared focal plane array) detector, a minicomputer, an infrared total reflective mirror I, an infrared total reflective mirror II and a lens III. The whole device is protected and fixed by using the light-tight shell, only two circular hole positions are reserved on the device for inlaying the lens I and the lens III, interference of invisible lights is avoided, imaging quality is improved, the infrared holographic technology is adopted and used for searching and rescuing on the fire scene, the flame or smoke can be penetrated effectively on the fire scene, conditions in the rear of the flame or smoke are imaged and displayed, a to-be-rescued personnel searching and rescuing speed of the firefighters on thefire scene is improved, and searching and rescuing accuracy is improved.

Description

technical field [0001] The invention relates to the application field of infrared holography, in particular to a fire search and rescue device based on infrared holography technology. Background technique [0002] Fire is one of the common disasters that threaten the safety of people's lives and properties. It is undoubtedly a very important issue for firefighters to quickly and effectively find rescuers who are hidden behind flames or smoke at the fire scene. Although fire-fighting equipment is more and more advanced, there is still a lack of substantive solutions to the problem of how quickly firefighters at the scene of a fire can find the people to be rescued who are blocked by flames or smoke. [0003] Traditional holographic technology has gradually matured in real-time imaging and is used in various measurement and imaging. Since the laser light source used in traditional holography is generally in the visible light band and is greatly affected by flames or smoke, it ...

Problems solved by technology

[0006] In view of the above problems, the present invention applies infrared holographic technology to the search and imaging of rescuers who are blocked by flames or smoke at the fire scene, and proposes a fire search and rescue device based on infrared holographic technology, which can not only penetrate smoke imaging, but also It can penetrate flame imaging, overcome the shortcomings of existing infrared thermal imagers that cannot penetrate flame imaging, and is used by firefighters to quickly understand the situation behind flames or smoke at the fire scene and to rescue personnel who are blocked by flames or smoke rapid search and rescue
