Night vision technology has opened up a wide range of possibilities. Before the development of night vision, we could only see and observe objects those are visible to the naked eye Mark Stuart Jets Jersey , that too under light. Night vision enables us to see clearly in extreme low light conditions. With the help of a night vision device like monocular or binocular, you can clearly see a person standing hundreds of yards away on a dark moonless night with cloud in the sky. There is such advanced technology that might enable you to view objects even in pitch black condition. What is not visible to the naked eye even under light may be perceived with the help of heat sensing night vision devices.

Application of night vision

Night vision devices find application in a number of fields. One of the most important applications of night vision devices is in military activities, especially in the dark. High range monocular devices are often mounted on guns and rifles, which help in spotting and hitting targets under very low light. Night vision devices are also used by the military or law enforcement departments for the purpose of surveillance at night. There are strategically placed surveillance cameras those have night vision technology built in them. Night vision is also applicable to wild life observation and supervision. In the jungles Mark Scheifele Jets Jersey , a lot of activities occur nocturnally.

Different technologies used

Two distinct technologies are used in developing night vision devices. The first one is image enhancement process. A device that enables night vision captures a tiny amount of light reflected by objects under dimly lit conditions. This light passes through a series of plates like a photo cathode, a high voltage micro channel plate and finally a green phosphor screen. As it passes through these layers, the light gets amplified before reaching the observer’s eyes. An example of such a device is Night vision Goggles. The other method is called thermal imaging. The upper part of the infrared spectrum emitted by objects are captured and transformed into visible images by the device. The user can view and distinguish between objects in absolute darkness based on the heat they emit.

Digital night vision

Today, night vision technology has taken a new leap with the advent of digital technology. Devices with Night Vision Digital have a number of advantages over traditional analogue systems. Digital systems can handle light of any intensity. Analogue systems are not built to deal with bright lights. Video recording facilities are easily integrated with digital systems whereas Logan Stanley Jets Jersey , for traditional devices, additional pieces of equipment are needed to be attached.
