Recently, snowfall has ushered in many places in China, and the withered yellow earth glows with a unique romantic color against the background of snow, which is intoxicating. Many tourists go to the mountains and forests to experience this fairytale-like world in depth.
China is a large country in terms of forest holdings, and because of the great importance attached to ecological protection, the amount of forests in China is increasing year by year. As of now, the current forest area of our country is 346.5 billion mu, with a forest coverage rate of 2402%, accounting for 54%。
Such a huge green resource gives people a lot of opportunities to get close to nature and feel nature. Whether it's a long-distance trip or a short-distance trip, tourism to experience mountains and forests is always an important option in many destinations.
The greenery in the summer, the snow-capped in the winter, and the high humidity of the forest in all seasons, often accompanied by clouds, are important reasons for the influx of tourists.
Although the scenery is beautiful, there are also certain dangers in the forest. Forests in spring and winter are prone to fires due to dryness, while clouds and fog are caused by rain, snow, and high humidity, which can lead to turning and getting lost. Once you encounter an unexpected forest fire or get lost in the clouds, it is easy to pose a threat to life safety.
However, the existing search and rescue equipment faces a sense of powerlessness in the face of penetrating high-temperature smoke thermal imaging or penetrating fog imaging.
At present, some equipment can achieve the realization of a single technology, but it is still difficult to achieve a variety of imaging requirements together. And buying a variety of imaging equipment is even more unrealistic.
Therefore, it is very important to have an imaging equipment that can comprehensively penetrate smoke imaging, fire penetration imaging and other imaging without fear of environmental interference.
The penetration imager, using advanced optical imaging technology, can penetrate the medium such as rain, snow, high temperature smoke, fog, haze, fire, strong light, etc., so as to achieve the imaging instrument behind the medium.
The interior is mainly composed of near-infrared pulsed lasers, image-enhanced strobe cameras, beam expanders, imaging lenses, etc. Among them, the image-enhanced strobe camera has a built-in MCP (micro-channel board) image intensifier, high-voltage module, timing module, gating module, etc., which can achieve an optical gain of 10 6, an optical shutter of less than 3ns and a timing synchronization accuracy of better than 10ps, which can realize high-precision three-dimensional information acquisition of the target.
With this equipment, during the key protection period of the forest, the penetration imager can carry out strong light suppression imaging without fear of strong light in summer, and eliminate the blind spot caused by strong light.
It can be free from rain, snow and haze interference, and realize clear observation all day and all day, so as to ensure the safety of the jurisdiction.
In the event of a fire, it can help search for trapped people without fear of high temperature smoke and flame interference, and avoid the danger of not being searched because the human body temperature is lower than the temperature of the fire site.
Penetration imager, which can fundamentally eliminate optical media interference. It is hoped that through this new optical imaging equipment, it will make a modest contribution to the protection and rescue of forest science and technology.
