Function and Type Night Vision
Night vision is the ability to see the good in the sense with biological or technological capabilities in dark environments. Night Vision is a tool that can be used or have the ability to view or take pictures in night conditions. A Night Vision device actually works two different ways depending on the technology used. First, by strengthening the image. This method works by collecting a small amount of light, including a piece of the spectrum of infrared light captured, which exists but may not be seen by the naked eye, and then reinforce it so that the image can be seen easily. Second, with the heating system image. This technology operates by capturing the highest part of the spectrum of infrared light, which is emitted by the object being described as light. Hotter objects such as human body heat, emitting more light than cooler objects like trees or buildings.
