In a night vision tube, the object of the tube is to convert incoming light particles (photons) to electrons. The electrons are then multiplied many times by the microchannel plate inside the tube. It is these multiplied electrons that are the output 'signal'. However, since your eye cannot see electrons, they are converted back to visible light by way of the phosphor screen which 'lights up' when energized by the electrons.

What is the difference between pir movement sensor and ir sensor?
Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.
