Night-vision device capable of cleaning and filling in light automatically

Abstract

The invention discloses a night-vision device capable of cleaning and filling in light automatically. The device comprises an object lens, a CCD imaging module, a master control ASIC, an infrared illuminating apparatus, a cleaning fluid storing device, a cleaning liquid ejector, an illuminance detection head, a microphone, a minitype liquid crystal display, an eye lens and a power source module. By arranging the cleaning fluid storing device additionally in the device, when in a rainy day or in a heavily dewy day, ejection action of the cleaning liquid ejector is controlled through the master control ASIC, cleaning liquid in the cleaning fluid storing device is ejected to the surface of the object lens, a cleaning liquid layer is formed on the surface of the object lens, due to the fact that the cleaning liquid is large in tension, the flow velocity of water drops on the surface of the object lens can be sped up, so that rainwater or fog water cannot adhere to the surface of the lens, and the shot image quality under the rainy or foggy environment is improved.

Description

technical field [0001] The invention relates to an imaging device, in particular to a night vision device for automatically cleaning and supplementing light. Background technique [0002] The night vision device is a nighttime external sight with an image intensifier as the core device, and 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. Infrared night vision device is a military night vision device using photoelectric conversion technology. It is divided into two types: active and passive: the former uses infrared searchlights to irradiate the target, and receives reflected infrared radiation to form an image; the latter does not emit infrared rays, but relies on the target's own infrared radiation to form a "thermal image", so it is also called "thermal image". instrument". [0003] Visible light at night is...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a night vision device with automatic cleaning and supplementary light, which solves the problems of large volume and long length, uneven light and poor imaging quality caused by constant infrared irradiation at the same time, and achieves the same The purpose of shortening its length and improving imaging quality under the condition of magnification
