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
The present invention relates to picture pick-up device, specifically refer to a kind of night vision device of automatic cleaning light filling.
Background technology
Night vision device take image intensifier as the outer gunsight at night of core devices, and utilize faint light on phosphor screen, to strengthen by image intensifier the visual picture can experienced for human eye according to lower target institute reflection ray to observe and run-home.Infrared viewing device is the military night vision instrument utilizing photoelectric conversion technique.It is divided into active and passive type two kinds: the former forms image with infrared searchlight light irradiation target, the infrared radiation receiving reflection; The latter does not launch infrared ray, relies on the infrared radiation of target self to form " heat picture ", therefore is also called " thermal imager ".
Night, visible ray was very faint, but infrared ray invisible to the human eye is very abundant.Infrared ray can help people to carry out observing at night, search for, aim at and steering vehicle depending on instrument.Although people have found infrared ray very early, be subject to the restriction of infrared components and parts, infrared remote sensing technology development is very slow.Until after Germany in 1940 develops vulcanized lead and several infrared transmission material, just make the birth of infrared remote sensing instrument become possibility.After this first Germany develop several infrared acquisition instruments such as active infra-red night vision device, once with the contact battle of armored column of the British army, the German army's leopard formula tank being equipped with infrared sight collimation device is smashing Liang Liang British army firefly tank at one stroke, it is worth mentioning that, the Sino-German army of this campaign uses passive type infrared night vision device, therefore fight time also have a cat owl infrared searchlight car in the distance with infrared ray be leopard formula tank throw light on.
Current night vision device, usually all only adopt infrared ray as light source, but such night vision device is doomed to have infrared ray hot spot and is appeared at night vision device surface, also appears in monitoring area, is unfavorable for that undisturbed monitoring is taken, secondly, its length of current night vision device is comparatively large, and multiplication factor is higher, and its length is larger, its multiplication factor is that the adjustment relying on object lens itself realizes, and greatly limit its size.
Summary of the invention
The object of the present invention is to provide a kind of night vision device of automatic cleaning light filling, solve that the volume that current night vision device exists is large, length is large, infrared ray irradiates the problem that light is uneven, image quality is poor brought always simultaneously, shortens its length, improves the object of image quality when reaching identical multiplication factor.
Object of the present invention is achieved through the following technical solutions:
