ABSTRACT

Night Vision technologies encompass techniquesof image conversion, image intensification andthermal imaging. Each has distinct

characteristics and capabilities.

The current image intensification technology --utilizing photocathode, phosphor screens andmicro channel plates -- illustrates the technologyof light amplification and image resolution.

INTRODUCTION Till now, Visualizing objects at night has been a

herculous task for human eye without havingsufficient light sources.

But now in this century, we have overcome thisproblem with a greater solution for this problem.

NIGHT VISION TECHNOLOGY

Which gives usthe ability to see in conditions that are too dark for anaked eye.

What is Night Vision?

Night Vision is an optical device consisting of high-quality image intensifier tubes and optics that amplifyexisting light.

It has an Infrared Illuminator, which provides a lightsource for the system to amplify the images.

It can give you the enhanced images in very low light

conditions, such as caves, where no ambient light isavailable for amplification of the objects inside.

HISTORY NVDs have been around for more than 40 years.

They are categorized by generations.

Each substantial change in NVD technology

establishes a new generation.

GENERATION 0

GENERATION 1

GENERATION 2

GENERATION 3

TECHNOLOGIES

With the proper night-vision equipment,you can see a person standing over 200 yards(183 m) away on a moonless, cloudy night.

Night vision can work in two very differentways, depending on the technology used.

ADVANTAGESWith the proper night-vision equipment, we

can see a person standing over 200 yards (183 m)away on a moonless.

More flexible in Locating enemy targets inMilitary.

Most useful for the experiments carried out in

the Darkness.

CONCLUSION

Although the term Night Vision currentlyencompasses three distinct technologies,it is the evolution of image intensification

technology that first made devicespractical and widely used. Their successwas the result of advancements in light

amplification and resolution techniques.
