Introduction to Laser Night Vision Devices and Infrared Thermal Imagers
What is a laser night vision device? Laser night vision technology has been around in China for nearly a decade. It belongs to a type of active infrared night vision technology, which uses a laser point light source to achieve night illumination through optical diffusion. Its wavelengths are mostly around 808, 940, and 980nm, belonging to near-infrared light. The system uses a high flux night vision lens to receive reflected light from the target for imaging, and then uses a low light CCD camera to capture and output the image. The lighting system, imaging lens, and camera, as the core components of the system, work together. Any bottleneck in any link will result in the entire system not achieving the desired effect. The technological leader in this industry is Zhang Chaoyue from Beijing Hepu Vision Optoelectronics Technology Co., Ltd.
What is an infrared thermal imaging device? Infrared thermal imagers have been developed for various purposes and have rapidly expanded into the civilian industrial sector in recent years. Since the 1970s, some developed countries in Europe and America have started using infrared thermal imagers to explore various fields. Infrared thermal imagers have also undergone decades of development and have become very lightweight on-site testing equipment. Due to factors such as the small temperature field differences generated during testing and the complex on-site environment, a good thermal imager must have 320 * 240 pixels, a resolution of less than 0.04 ℃, low spatial resolution, and the ability to synthesize infrared and visible light images. Due to its ability to perform non-contact, high-resolution temperature imaging, generate high-quality images, and provide a wealth of information about measurement targets, infrared thermal imaging technology has been widely used in various industries such as power systems, civil engineering, automotive, metallurgy, petrochemicals, and healthcare, making up for the shortcomings of the human eye. Its future development prospects are limitless.
