Night Vision Technology

About Night Vision Technology

Night vision Technology is mostly used in the military and the secret Security Agencies. This technology is not available in market for everyone. By using this Technology one can see in the darkness in the dim light places. Night vision technology is the general term used furthermore this technology is divided into three types .

First is low light imaging 

Second is thermal imaging 

Third is near infrared illumination 

The three kinds of night vision Technology would be discussed in some details here. Almost every kind of night vision Technology has goggles. By using that goggles one can use the technology of night vision. 

Thermal Imaging Technology

In thermal imaging technology the infrared light is detected, it means that in the darkness there may be infrared light that is not visible to naked eye by using the night vision goggles that available light is collected even the infrared light is collected to enhance and increase by the light so that it can be seen what is going on in the darkness.

As it is visible from the name thermal imaging technology from thermal means about heat so the goggles of thermal imaging Technology act like to detect the heat of living things. Call every living thing has some temperature that's not possible that the living thing would be cold enough and not detectable by the thermal imaging, that is not detectable by the thermal imaging goggles that would be dead.

Low Light Imaging Technology

In low light imaging Technology the light is amplified to create a vision in the low light area. The common method light imaging is often called as image intensifier in this method the available light is amplified. The basic operation of low light imaging as follows 

The available light in the low light area is focused throw the objective lens on a photo cathode of the image intensifier. 

By using the electric field electron accelerated which was released by cathode. 

The accelerated electrons are directed toward the microchannel players and they begin to bounce with internal walls creating new bouncing electrons. 

Then there is used phosphor screen, that accelerated and bounced electron are directed to hit the phosphor screen to generate phosphor glow. 

And that glow if the desired vision.

Near Infrared Illumination

Near infrared illumination is the technique of night vision technology in with the device which is sensitive to The Invisible near infrared radiation is used along with infrared illuminator. This is the most popular method used in the night vision Technology and this is also the most inexpensive method of night vision. Another word in the near infrared elimination method the infrared radiations are detected to create a clear vision for example in the camera recorders this technology is used to get the clear image quality low light.

The night vision technology is not accessible by a common man this is some kind of secret gadget used by military purpose and private security companies to protect their object.The night vision Technology is a great revolution in the field of Technology.
