Night Vision
Night Vision
Night vision is the ability to see at night or in the dark when it would otherwise be impossible to see. This ability is made possible through special tools that are created via one of the following two approaches: 1. Suficient Spectral Range or 2. Sufficient Intensity Range. Sufficient spectral range allows a person to see light in his surroundings that the human eye cannot normally detect. Sufficient intensity range helps a person to see when there is only a small quanity of light available by helping the human eye to detect single photons.
