What is Laser Night Vision and Infrared Thermal Imager
What is a laser night vision device? Laser night vision technology has appeared in China for nearly ten years. It is a kind of active infrared night vision technology. Its principle is to diffuse the laser point light source through optics to achieve the purpose of night lighting. Its wavelengths are mostly 808 and 940 , 980nm, which belongs to near-infrared light. The system uses a high-throughput night vision lens to receive the reflected light of the target for imaging, and then uses a low-illuminance CCD camera to collect and output the image. As the core components of the system, the lighting system, imaging lens, and camera cooperate with each other. A bottleneck in any link will cause the entire system to fail to achieve the desired effect.
What is an Infrared Thermal Imager? Infrared thermal imaging cameras were first developed for medical purposes, and have rapidly expanded to civilian industrial fields in recent years. Since the 1970s, some developed countries in Europe and the United States have successively started to use infrared thermal imaging cameras to explore in various fields. Thermal imaging cameras have also evolved over decades into very portable field test equipment. Due to factors such as small temperature field differences and 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, provide a lot of information on measurement targets, and make up for the lack of human eyes, it has been used in power systems, civil engineering, Automobile, metallurgy, petrochemical, medical and many other industries have been widely used, and the future development prospect is even more limitless.
