Cheap Night Vision Goggles
The night vision systems that allow viewers to observe objects at night are night vision goggles. These work in the dark and provide good quality images.
The night vision goggles function as follows:
Light from an existing source like the moon or the stars is gathered by the front lens of the night vision goggles. This light then travels to the photocathode tube which converts the photons into electrons. Different chemical and electrical processes are applied to the electrons to increase them in number. The electrons then strike a phosphorous screen where they are converted back to visible light and the image thus formed is viewed by the observer.
