Abstract
Apparatuses, systems and methods are disclosed for reducing interference between an active illumination device and external radiation sources, for example, other active illumination devices operating within the vicinity. A disclosed system includes one or more active illumination devices, each configured to emit an illumination signal and also to receive a returned portion of its respective illumination signal with at least one sensor. At least one of the active illumination devices is capable of detecting interference caused by an external source, for example, an illumination signal emitted from another active illumination device. As a result of detecting the interference, the receiving active illumination device changes the timing of its subsequent illumination signals and sensor operation. By detecting collisions between illumination signals and consequently altering the timing of it operation, the active illumination device may reduce interference in congested environments where multiple active illumination devices are operating within range of each other.
