Interferometric system for selecting spectral components of an optical beam

摘要

The system has an interferometer (41) separating an optical beam into two optical beams. A multiplexer/demultiplexer imager (42) spatially demultiplexes the beams based on spectral components. A phase shifter (43) shifts the demultiplexed beams to produce out of phase beams. A mirror (44) reflects the out of phase beams to produce two output beams that are multiplexed in wavelength and have components of the out of phase beams.
