Life cycle of night vision goggle: A brief history!

Over the years we have seen monumental change in science and technology and how it has worked for the betterment of mankind. Each invention has its own life cycle. It has to go through various stages of development to become better and efficient. Invention of night vision goggles is no exception to it. This device also had to go through various stages of development. Those stages are called generations in the case of this goggle. Let’s discuss various stages of development of the goggle for better understanding of its life cycle.

Generation 0
Invention of the goggles which can enable us to see in night can be attributes to World War 2. Both USA and German army wanted to continue their combat after dark hence invention of the device took place. 0 generation devices used large infrared illuminators to capture the image and they were called active devices.

Generation 1
Unlike generation 0, this generation goggles were passive devices. It was mainly used during the Vietnam War. This type of goggle was mainly developed due to the development of star light technology. These goggle used the moonlight to produce an image. It also magnified the image by 1000x.

Generation 2
This generation saw a drastic improvement in the quality, efficiency, resolution, magnification and image quality of the goggles. They were mainly developed with the aim of using it on a moonless night. Now you could see in total darkness with the help of generation 2 goggles. They good magnify the image up to 20000x.

Generation 3
This generation has also seen dramatic improvement in the efficiency, resolution, magnification and image quality of the goggle. It can now zoom the image by 30000x to 50000x. Increased service life of intensifier tube makes it ideal and most preferred to be used in US military.

Generation 4
This generation is being developed to make the performance of the goggle much better and advanced. We are yet to find its commercial viability and service life of the intensifier tube.
