What is the night vision digital?

devices night vision conventional use a tube image intensifier (IIT). In addition, the oscilloscopes numéamericas (DNV) use of devices to charge-coupled (CCD) or semi-conductors à oxide métal complételephone (CMOS) and micro-displays. The lumière draftée of the lens on the rébucket CCD or CMOS is converted into a signal éelectric. The signal is then traité and envoyé to the microdisplay to &stop;tre seené by the user.

The CCD and CMOS sensors are more sensitive to near-infrared as the IIT and can see the lumière above 1000 nm. In contrast to IIT, night vision numéamericas, nécessitent the addition of lumière of artificial créer of the bright images, but the devices of night vision numédevices can &stop;tre utilisés à la lumière of the day. They can éalso save images directly on a map, mémoire internal or on the DVR via an output vidéo. DNV is désormais a viable alternative to night vision génération 2, because the figures provide performance and a résolution similar, but à a cost comparable to or inférieur à the secondème génération.

night vision numédevices, such as the fant&taxes;my, nécessitent a source of lumière, external déto detect clear images with a lumière weak and without lumière. The infrared illuminators can générer enough lumière sans dédetect animals or the other to clearly identify the target in the dark.

Two types of résolutions are énumérés Spéspecifications night vision numéamerica. The résolution of sensor - éalso résolution capturing - is the résolution of sensor d’imaging. The résolution on display is the résolution to the display or the image that the user sees and must not &our vision to be confused with the résolution of sensor. The résolution is the number of pixels in the sensor array or the display. These figures refer to the total number of pixels on the width and the height of the sensor or of the’display. A résolution de 800 x 600 means that l'écran or the sensor has a width of 800 pixels and a height of 600 pixels. Général, the higher the number, the more the image is défurnishée. For the imaging sensors, the more pixels on the sensor array, the greater the quantityé de lumière capturée will be large, which increases généusually the brightnessé résolution and the viewing distance of the image.

Those who possètooth mirrors à rifle, night vision, numéric or expéperience thermal imaging do not have any difficulté à configure lunette de visée, but those of us who need help supplé; in the dédepartment ée may encounter problèmes without instructions spéis installed.

I strongly recommend that you familiarize yourself with its menus and its paramètres before the’use. Once familiarisé with its operation, aim à of the house before you head into the line of fire. This will cause you to ésaving a lot of ammo, time and frustration.
