Abstract
An apparatus and method are provided to spatially multiplex information into a rainbow spectrum by filtering out certain frequencies or colors of the spectrum. The frequencies that are filtered or blocked out may depend on a value of a system input such as a level indicator, temperature gauge, pressure indicator, and the like. The spectrum, absent the filtered out frequencies, is sequentially focused into a single composite beam for transport through an optical path or fiber. Upon arrival to a destination, the composite beam is spatially separated into the original rainbow spectrum and projected onto a display. A viewer may subsequently view the spectrum and any dark areas within the spectrum associated with filtered or blocked frequencies and may, therefore, monitor a remotely located system.
