Noktovizor

The nightclub allows a dark, starless night to be seen as clearly as a person sees with unarmed eyes in sunny weather. With the help of a lecturer can watch through thick fog and a thick layer of clouds. In fact - it's a night electric binocular.

Noktovizor can be used in laboratories and in production, to monitor the processes that must be conducted in very low light.

All bodies emit infrared rays, invisible to humans. This is taken into account when constructing a noctivisor. The problem of converting infrared rays into visible light rays can be solved in two steps.

Infrared rays, falling on a layer of sodium, potassium or rubidium compounds, tear out electrons from it, and in order to convert the flow of electrons into visible light, a known physical phenomenon, luminescence, is used in the lecturer. Electrons, striking against a layer of phosphors, make them glow.

In order for the luminescence to be intense, electrons must have a high speed. The speed of electrons, extracted by infrared rays, is insignificant. Therefore, the motion of these electrons must be accelerated by an electric field. An electric field with a voltage of about 4 thousand volts is created with the help of a battery.

The device weighs about 150-200 grams. On a motor vehicle, on a locomotive, on a ship and on an airplane, the battery can be placed separately in any place and connected to a lecture device using flexible wires.
