    The Science Behind Night Vision Goggles

    Night vision goggles’s end purpose is to give the user a clear and consistent picture while using the night vision goggles. For to do this, modern night vision goggles doesn’t produce light, but night vision can use CMOS technology to let people see anything at night. It accomplishes this through a series of simple steps.

    The night vision goggles has to happen is some form of light has to enter through the front lens of the night vision goggles. This light can come from anywhere, including the moon or stars. As the light reflects off of everything else, it produce even more light. Reflection is a must-have for night vision goggles.

    Our night vision use CMOS technology is the semiconductor technology used in the transistors that are manufactured into most of today's microchips. Semiconductors are made of silicon and germanium, materials which "sort of" conduct electricity, but not enthusiastically. Areas of these materials that are "doped" by adding impurities become full-scale conductors of either extra electrons with a negative charge (N-type transistors) or of positive charge carriers (P-type transistors). In CMOS technology, both kinds of transistors are used in a complementary way to form a current gate that forms an effective means of electrical control. CMOS transistors use almost no power when not needed. As the current direction changes more rapidly, however, the transistors become hot. This characteristic tends to limit the speed at which microprocessors can operate.

    You have to understand that light is made of photons. These photons enter the device through the front lens and reach something called the photocathode. The photocathode then takes those photons and converts them into electrons.  The electrons then meet something called a photomultiplier. This is a type of photoelectric cell. Here the electrons are multiplied over and over again to create tons of electrons.  

    The end result is a much brighter and clearer picture of whatever the device is looking at. This is an easy explanation of how night vision works. What’s amazing is that all of this happens instantly. Simply turn it on, and bam! The world is glowing black white light around you.
