Laser night vision instrument

Laser night vision instrument

Composition of laser night vision device: internal industrial-grade embedded control electronic system, which realizes high stability control of camera magnification, focusing, video switching, pan-tilt pitch/rotation. The overall shell adopts super aluminum alloy to reach IP66 protection grade, ensuring long-term operation of the equipment in harsh field ring mirror. Laser night vision features: color to black and white: using ultra-low illumination infrared camera design, with laser infrared lighting system, to achieve color during the day and night black and white all-weather real-time monitoring. Adjustable laser spot: Using special laser electric lens, the illuminance angle and light intensity of the laser spot can be adjusted in real time to realize no blind spot night

Classification of Photoelectric Imaging Systems

Classification of Photoelectric Imaging Systems

It is divided into active imaging system and passive imaging system, direct-view imaging system and inter-view imaging system, low-light imaging system and infrared imaging system. Photoelectric imaging systems are divided into three categories according to the objective lens system: refractive system, reflective system and catadioptric system. Refractive system Refractive objective system is easier to correct aberrations, can obtain a larger field of view, simple structure, easy alignment. Refractive objective lenses commonly used in optical systems are of the double Gauss type and the Pitzvat type. Reflective system reflective objective lens can be made into a large aperture, and the focal length can be longer, easy to obtain, that is, metal materials can be used, or ordinary glass can be used to plate a layer of metal on it.

Photoelectric imaging system

Photoelectric imaging system

Direct-view imaging systems include active infrared imaging systems and low-light imaging systems. They consist of an objective lens group, an image tube and an eyepiece group, and the human eye observes the target image on the fluorescent screen of the image tube through the objective lens. Intervision imaging system is to directly observe the target image on the silver light screen of the monitor with the human eye. Such systems include low-light television systems and thermal imaging systems. The optical system of the low-light-level television system is mainly the low-light-level imaging objective lens; the optical system of the thermal imaging system includes the scanning optical system and the relay optical system in addition to the infrared imaging objective lens. No matter what kind of imaging system must have the corresponding optical system to image the scene on the photoelectric receiver, so the optical system is

Photoelectric reconnaissance

Photoelectric reconnaissance

Photoelectric reconnaissance, the use of photoelectric equipment to receive and process the target's own or reflected by its optical radiation, in order to find and identify the target's reconnaissance method. According to the reconnaissance environment, it is divided into ground reconnaissance, maritime reconnaissance, aviation reconnaissance and space reconnaissance; according to the working principle of the equipment, it is divided into visible light reconnaissance, infrared reconnaissance, laser reconnaissance, television reconnaissance, low-light reconnaissance, etc.; according to the working mode of the equipment, it is divided into active reconnaissance and passive reconnaissance. The equipment used for photoelectric reconnaissance mainly includes: (1) optical reconnaissance equipment, including telescope, reconnaissance theodolite, optical rangefinder, artillery mirror, periscope, compass, etc. (2) Night vision devices, including active infrared night vision devices, low-light night vision devices, low-light television, night vision glasses, and thermal imaging devices. (3) TV camera. (4) Multispectral photographic equipment. (5) laser range finder.
