Night Vision Optics

ABSTRACT

In this study we will attempt to disclose the major aspects of night vision technology and how it has evolved over the past forty years. Night vision is simply having the ability to see in the dark. In many night vision systems, the objective lens collects small particles of light called photons and focuses them on an image intensifier. Within the image intensifier lies a photocathode which absorbs light energy and converts it into electrons. When the highly intensified electron image strikes the phosphor screen, it causes the screen to emit light which can be seen with the human eye. This process allows one to see a reflected image that directly corresponds with the outside image they are viewing. Night vision technology is considered preeminent and is used throughout the world in various areas of life (“How Night Vision Works”).

INTRODUCTION

Have you ever got up in the middle of the night and stumbled over an object in the middle of the floor? Blinded by the darkness, you rush to the nearest light switch to get an illuminated view of the area. Well, stumble no more; through advancement in technology, special equipment has been produced to enable one to see through the darkness. We call these highly esteemed devices, night vision optics. Originally developed and used by the U.S. military to locate enemy targets at night; night vision optics or devices, better referred to as NVDs, have revolutionized the history of human vision.
