![]() ![]() These sensors are resistant to damage from a bright light. These two types of sensors exhibit sensitivity to a near-infrared spectrum. Digital night vision The least know of the three technologies, digital night vision, uses a CCD (charge-coupled device) or SMOS (complementary metal-oxide sensor) similar to a digital camera.With this technology, a device has an intensifier tube that converts the infrared light reflected from an object and transforms it into a visible image. Image intensifier This technology was first used in 1939, and everyone associates the green and black images with the term night vision.Under the term “Night Vision,” there are three generally accepted technologies. Through the decades, night vision technology has evolved, with equipment and performance increasing while prices have decreased. A mechanism to see in the dark was first used in World War II and came into full acceptance during the Vietnam War. Seeing in the dark by a human-made device was once the domain of only the military and law enforcement.
