it isnt all that easy…. night vision goggles project infrared light (the same type used by most television remote controls), and produce an image from the light reflected back. these goggles may require an image enhancer to amplify the light…. u can find that in video cameras.
the ther type of night vision goggles (passive) use use electro-optical tubes that amplify very low levels of light several thousand times using an image intensifier.as a photon collides with a detector plate, the metal ejects several electrons that are then amplified into a cascade of electrons that light up a phosphor screen. often a dim star in the sky is enough to illuminate an entire field.

One needs an infra-red receiver.
