Portable projectable infrared lights are used to mark and illuminate dark areas such as rooms in a building or cells in a prison. The lights cannot be seen with the unaided eye but are brilliantly visible with the aid of night vision goggles and similar infrared receivers and light transducers which convert infrared light to visible light. In those cases where potentially hostile individuals are equipped with night vision apparatus, the infrared lights can be used to temporarily blind, stun and/or disorient them. |
