Abstract
The present invention provides a method of using a laser lighting apparatus for fire rescue navigation in a smoke-filled structure. The laser lighting apparatus is portably carried at a user's body and directly operated by the user to perform the steps of turning the laser lighting apparatus on to output one or more coherent light planes; projecting the one or more coherent light planes on objects in the smoke-filled structure to produce one or more light stripes on surfaces of the objects; and identifying the objects in the smoke-filled structure from the one or more light stripes.
