Blog Introduction: You’ve seen night vision goggles in the movies and on TV, but what are they really? In this blog post, we’ll explore everything you need to know about night vision goggles, from how they work to the different types available. By the end, you’ll be an expert on night vision goggles and be able to make an informed decision about whether or not they’re right for you.
How Night Vision Goggles Work
Night vision goggles work by amplifying the available light so that you can see in the dark. This is accomplished through a process called image intensification. Image intensification involves converting the low-light photons into electrons and then amplifying those electrons so that they create a visible image on a phosphor screen. This process allows you to see objects in the dark that would normally be invisible to the naked eye.
There are two types of night vision goggles – active and passive. Active night vision goggles use an infrared illuminator to provide light for the image intensifier tube to amplify. Passive night vision goggles do not have an infrared illuminator and instead rely on ambient light, such as moonlight or starlight, to provide light for the image intensifier tube.
Types of Night Vision Goggles
There are four different generations of night vision goggles, each with its own advantages and disadvantages.
Generation 1
Generation 1 night vision goggles were first developed for military use in Vietnam and are now available to civilians. These entry-level devices produce a green monochrome image and have a short life span due to their high-intensity discharge (HID) arc lamps.
Generation 2
Generation 2 night vision goggles use a microchannel plate (MCP) in addition to an HID lamp, which provides increased amplification and improved clarity over Generation 1 devices. These devices also produce a green monochrome image.
Generation 3
Generation 3 night vision goggles use a photocathode tube with an MCP for increased amplification and clarity. These high-end devices produce a clear black-and-white image with very little distortion.
Conclusion
Night vision goggles allow you to see in complete darkness by amplifying the available light. There are four generations of these devices, with each generation offering improved performance over the last.
