Description

Technical Field

[0001] The utility model relates to the technical field of night vision devices, and specifically relates to a binocular night vision device. Background Art

[0002] A night vision device converts the light signals (low light or infrared light) that are invisible to the human eye from a target into electrical signals, then amplifies the electrical signals, and converts the electrical signals into light signals visible to the human eye, and further processes them into images, which can observe targets in the dark. Night vision devices are not only used in night investigations, arrests, search and rescue operations of security departments, but also widely used by individual users in outdoor activities such as sightseeing, tourism, and exploration. Most of the existing night vision devices are handheld or worn on helmets. When in use, the handheld night vision device needs to be held by the palm all the time. When observing at a fixed position for a long time, it not only affects the operation of both hands, but also causes discomfort in the arm. The night vision device cannot be directly worn on the head and needs to be installed on the helmet for wearing. For amateur enthusiasts or outdoor users, in order to facilitate outdoor activities, they will try to reduce the carrying of items.
