Types of Illumination

There are two types of illumination that assist engagement during low light or darkness: ambient light and artificial illumination. Both ambient light and artificial illumination can affect target perception (distance and size) and night vision capabilities.

i Ambient light is the light produced by natural means (i.e., the sun, moon, and stars). Variations occur in ambient light due to the time of day, time of year, weather conditions, terrain, and vegetation. i Artificial illumination is the light produced by a process other than natural means. Artificial light can be used to illuminate an area for target detection or to illuminate a specific target to pinpoint its position. There are two types of artificial illumination used in combat: air and ground.
