摘要: A system and method for distinguishing a first light source from other light sources utilizes an image receiver that can selectively engage and disengage a filter. The filter can be configured to block bands of light corresponding to the light being emitted by either the first source or the other sources. By alternately engaging and disengaging the filter from the image receiver, the first light source may be distinguished from other light sources.
