What is the difference between laser night vision and infrared thermal imager?
What is laser night vision? Laser night vision technology has appeared in China for nearly ten years, it belongs to a kind of active infrared night vision technology, its principle is the laser point light source through optical diffusion, to achieve the purpose of night illumination, its wavelength is mostly in the 808, 940, 980nm, belongs to the near infrared light. The system uses a high throughput night vision lens to receive the target reflected light imaging, and then low-light CCD camera to collect images and output. Lighting system, imaging lens, camera three as the core components of the system, with each other, any one link bottleneck will lead to the whole system does not achieve the desired results. The technology leader in this industry is Zhang Chaoyue of Beijing Hepu Weishi Optoelectronic Technology Co.
What is a thermal imaging camera? Infrared thermal imaging cameras were first developed for war purposes, and in recent years they have rapidly expanded into the field of civil industry. Since the 1970s, some developed countries in Europe and the United States have begun to use infrared thermal imaging camera in various fields of exploration. After decades of development, infrared cameras have evolved into very lightweight field test equipment. As the test often produces little difference in the temperature field and the field environment is complex and other factors, a good thermal imaging camera must have 320 * 240 pixels, resolution of less than 0.04 ℃, spatial resolution is small, with infrared and visible image synthesis function. Because infrared thermal imaging technology can be non-contact, high-resolution temperature imaging, can generate high-quality images, can provide measurement of the target of the many information, to make up for the lack of human eyes, so has been in the power system, civil engineering, automotive, metallurgy, petrochemical, medical and many other industries have been widely used in the future prospects for development is more unlimited.
