Abstract
A system includes at least one light projector, at least one image sensor, and at least one controller. The at least one light projector is attachable to an aircraft at a first location. The at least one light projector is configured to emit a first beam of light in a first direction at a first intensity. The at least one image sensor is attachable to the aircraft at a second location. The at least one image sensor is configured to capture a first image of a scene including reflections of the first beam of light and a second image of the scene without the at least one projector emitting a beam of light. The at least one controller is configured to determine a maximum detection range of the first beam of light based upon the light intensity of the light beam, the first location, and the second location.
