Description

technical field [0001] The invention relates to a night vision imaging technology, in particular to a helmet-type monocular wide-angle low-illuminance CMOS night vision device. Background technique [0002] Night vision device, a nighttime external sight with an image intensifier as the core device, does not use infrared searchlights to illuminate the target when it works, but uses the light reflected by the target under weak light to be enhanced on the fluorescent screen by the image intensifier into a visible image that can be perceived by the human eye To observe and aim at the target, it is widely used in military reconnaissance equipment. The night vision devices sold on the market are complex in structure and single in function. The application number is CN200920057545.0. A lens assembly, an imaging display and an eye cup device are sequentially installed on the body, a single-board computer camera assembly is arranged between the lens assembly and the imaging display,...

Problems solved by technology

[0002] Night vision device, a nighttime external sight with an image intensifier as the core device, does not use infrared searchlights to illuminate the target when it works, but uses the light reflected by the target under weak light to be enhanced into a visible image that the human eye can perceive on the fluorescent screen through the image intensifier To observe and aim at the target, it is widely used in military reconnaissance equipment. The night vision devices sold on the market are complex in structure and single in function. The application number is CN200920057545.0. A lens assembly, an imaging display and an eye cup device are sequentially installed on the body, a single-board computer camera assembly is arranged between the lens assembly and the imaging display, the imaging display and the single-board computer camera assembly are connected to the control assembly, and the control assembly is provided with a storage card interface, and a power supply device is also provided in the housing, which can be observed and monitored with the naked eye in a low-brightness environment. The image is saved by shooting or video recording, but this kind of night vision device is only used at night, and the range of use is small, so it is not convenient for long-distance use

[0003] In addition, the current night vision devices usually only use infrared rays as the light source, but such night vision devices are destined to have infrared light spots appearing on the surface of the night vision device and also in the monitored area, which is not conducive to undisturbed monitoring and shooting. Secondly, the current night vision device has a large length, and the higher the magnification, the longer the length. The magnification is realized by the adjustment of the objective lens itself, which greatly limits its size.
