Infrared thermal imaging technology is an image based on the temperature difference of object surface. The principle is that any object will emit different intensities of infrared radiation due to its own temperature. Infrared thermal imaging technol…

Lens, 3D and machine vision all belong to the application scope of optical lens. Lens is the core component of optical instruments, which can control the transmission, distribution and focus of light, so as to adjust the optical path, optical quality…

Environmental optics is developed on the basis of photometry, colorimetry, physiological optics, psychophysics, physical optics, architectural optics and other disciplines. It mainly studies the interaction between light and environment, including na…

Aviation refers to the navigation activities of aircraft in the earth’s atmosphere. This includes using aircraft heavier than air (such as fixed wing aircraft, rotorcraft, helicopter, etc.) and aircraft lighter than air (such as balloons, airsh…

Laser measurement is based on the high focus, high brightness and strong directivity of laser beam. When the laser beam strikes the surface of an object, reflection, scattering and absorption will occur. The laser measuring instrument emits a short p…

Laser imaging is based on the high focus, high brightness and strong monochromaticity of the laser beam. It mainly includes laser, lens, scanning device, receiver and other components. The laser is used to generate the laser beam, the lens is used to…

Laser illumination is a kind of illumination technology using laser beam as light source. By using a laser emitter (such as a laser) to generate a laser beam with high intensity and high directivity, and then focusing, diffusing or guiding the laser …

Lidar emits laser beam to the target, and then receives the laser signal reflected from the target. By comparing and processing the transmitted signal and the received signal, the distance, speed and other parameters of the target object can be calcu…

Laser cutting is to focus the laser beam with high power density on the surface or inside of the material to be cut. The energy of the laser beam rapidly heats the material to the threshold of melting, vaporization or combustion. At the same time, th…

The laser welding technology consists of an optical oscillator and a medium placed between the mirrors at both ends of the oscillator cavity. When the medium is excited to a high energy state, it starts to produce in-phase light waves and reflect bac…
