What are laser night vision and infrared Thermographic camera
What is a laser night vision device? Laser night vision technology has been emerging in China for nearly a decade. It belongs to a type of active infrared night vision technology, and its principle is to diffuse a laser point light source through optical means to achieve nighttime illumination. Its wavelengths are mostly 808, 940, and 980nm, belonging 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 illumination CCD camera to collect the image and output it. The lighting system, imaging lens, and camera, as the core components of the system, cooperate with each other. Any bottleneck in any link will result in the entire system not achieving the desired effect.
What is an infrared Thermographic camera? Infrared thermal imagers have long been developed for their purpose and have rapidly expanded into civilian industrial fields in recent years. Since the 1970s, some developed countries in Europe and America have started exploring various fields using infrared thermal imagers. Infrared thermal imagers have also developed into very lightweight on-site testing equipment after decades of development. Due to factors such as small temperature field differences and complex on-site environment during testing, a good thermal imager must have 320 * 240 pixels, a resolution less than 0.04 ℃, small spatial resolution, and the ability to synthesize infrared and visible light images. Due to the ability of infrared thermal imaging technology to perform non-contact, high-resolution temperature imaging, generate high-quality images, provide numerous information about measurement targets, and make up for the shortcomings of the human eye, it has been widely applied in many industries such as power systems, civil engineering, automotive, metallurgy, petrochemical, medical, etc. Its future development prospects are even more unlimited.
