Description

Technical Field

[0001] This utility model belongs to the field of night vision equipment technology, specifically relating to a portable head-mounted digital night vision observation device. Background Technology

[0002] Night vision devices are external sights used at night, with an image intensifier as their core component. They do not require an infrared searchlight to illuminate the target; instead, they utilize the light reflected from the target under dim lighting conditions, which is then amplified by the image intensifier onto a fluorescent screen to create a visible image perceptible to the human eye for observation and aiming. They are typically used in military applications, but currently also have wide applications in civilian and security sectors.

[0003] Existing head-mounted digital night vision observation devices are large, heavy, inconvenient to operate, and even more inconvenient to carry, thus limiting their practical application and fields. To address this, we propose a portable head-mounted digital night vision observation device that is easy to carry, compact in size, and easy to operate. Utility Model Content
