Represent the night vision devices are an important part of the auxiliary devices in military operations and policing, can the wearer see clearly in the pitch dark, so how to operate Night Vision devices?
There are two co-chairmen of Night Vision devices, one of which uses light in the visible spectrum the near-infrared, where the lens to focus the light in the tube cathode, to convert light photons to an avalanche of electrons that take the form of photons coming from the body to see it.
He says another part in this type of Night Vision devices to magnify the flow of electrons, pushing them to a screen of phosphorus, which is available in contact with the electrons, leaving the color of the green trying to the form of the body to see it.
The second type of Night Vision devices working in the infrared range of the spectrum, which depends on the scientific truth that produced all living organisms, and energy of thermal, where the accurate calculation of heat configure the Heat Map of the scene to see it, and turns it into an electrical signal replenished at a rate of 30 times per second, and display the scene on a pair of small screens in front of the eyes of the user of the device.
