Abstract
A method for displaying information via a light source on rotating helicopter blades of an aircraft such as a helicopter is provided. The light source may be a laser light source and the light therefrom may be directed onto the aircraft blade by one or more motion controlled mirrors and a computer controller. A sensor is capable of determining the position of helicopter blades during rotation, such that light may be projected upon only the moving blade at precisely timed intervals, so as to form perceivable graphics and/or messages thereon. In addition, the method may be utilized for displaying graphics and/or messages on rotating propellers of fixed wing aircraft.
