indirect illumination
mil., logist. Battlefield illumination provided by employing searchlight or pyrotechnic illuminants using diffusion or reflection: 1. Illumination by diffusion: illumination of an area beneath and to the flank of a slightly elevated searchlight or of pyrotechnic illuminants, by the light scattered from atmospheric particles. 2. Illumination by reflection: illumination of an area by reflecting light from low cloud. Either or both of these effects are present when a searchlight is used in defilade or with its beam spread to maximum width. (FRA)
