Abstract
An addressable illuminator is disclosed consisting of multiple optical sources used in combination with an electrical circuit so that different combinations of the optical sources can be energized without exceeding eye-safety limits. Operation of multiple optical sources may be proximate, which is eye-safe, regardless of the number of or which ones of the optical sources are energized and regardless of the position of observers. An illuminator with multiple optical sources remains eye-safe when there are single-point electrical failures, such as short circuits, in the driving circuit. Monitoring or a feedback loop for the output power is not required or necessary to control the distance of an observer in order to be eye-safe.
