What is laser night vision and infrared thermal imaging camera
What is a laser night vision device? Laser night vision technology has appeared in China for nearly ten years. It is a type of active infrared night vision technology. Its principle is to diffuse laser point light sources through optical diffusion to achieve the purpose of night lighting. Its wavelengths are mostly 808 and 940 , 980nm, belongs to near-infrared light. The system uses a high-light-passing night vision lens to receive the target's reflected light for imaging, and then uses a low-illumination CCD camera to collect and output the image. The lighting system, imaging lens, and camera are the core components of the system and cooperate with each other. If a bottleneck occurs in any link, the entire system will not achieve the desired effect.
What is an infrared thermal imager? Infrared thermal imaging cameras were first developed for military purposes and have rapidly expanded to the civilian industry in recent years. Since the 1970s, some developed countries in Europe and the United States have begun to use infrared thermal imaging cameras to explore in various fields. Infrared thermal imaging cameras have also developed into very lightweight field testing equipment after decades of development. Due to factors such as the small temperature field difference often generated by tests and the complex on-site environment, a good thermal imager must have 320*240 pixels, a resolution of less than 0.04°C, a small spatial resolution, and the ability to synthesize infrared images and visible light images. Because infrared thermal imaging technology can perform non-contact, high-resolution temperature imaging, generate high-quality images, and provide a lot of information about measurement targets, making up for the shortcomings of the human eye, it has been used in power systems, civil engineering, It has been widely used in many industries such as automobiles, metallurgy, petrochemicals, and medical care, and its future development prospects are even more unlimited.
