ABSTRACT
Night Vision technologies encompass techniques of image conversion, image intensification and thermal imaging. Each has distinct characteristics and capabilities.
The current image intensification technology -- utilizing photocathode, phosphor screens and micro channel plates -- illustrates the technology of light amplification and image resolution.
INTRODUCTION
Till now, Visualizing objects at night has been a herculous task for human eye without having sufficient light sources.
But now in this century, we have overcome this problem with a greater solution for this problem.
NIGHT VISION TECHNOLOGY – Which gives us the ability to see in conditions that are too dark for a naked eye.
What is Night Vision?
Night Vision is an optical device consisting of high-quality image intensifier tubes and optics that amplify existing light.
It has an Infrared Illuminator, which provides a light source 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 is available for amplification of the objects inside.
CONCLUSION
Although the term “Night Vision” currently encompasses three distinct technologies, it is the evolution of image intensification technology that first made devices practical and widely used. Their success was the result of advancements in light amplification and resolution techniques.
