I-WMOSS: Interferometric wavelength multiplexed optical scanning sensor

Proposed is an electronically agile optical scanning sensor based on wavelength multiplexed optical interferometry. The basic design uses wavelength tuning to enable an optical scanning beam and a wavelength dispersive element like a grating to act as a beam splitter and beam combiner to create the two beams required for interferometry. A compact no-moving parts and environmentally robust design of the sensor is shown that enables an all-fiber in-line low noise delivery sensor using a fiber circulator, optical fiber, and fiber lens connected to a Grating-optic and reflective media sensor chip. The proposed fiber-remoted all-passive sensor can be used in numerous sensing applications where compact size and remoting is highly desired.
