Agile high sensitivity optical sensor |
摘要 |
An agile optical sensor based on scanning optical interferometry is proposed. The preferred embodiment uses a retroreflective sensing design while another embodiment uses a transmissive sensing design. The basic invention 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 and environmentally robust version of the sensor is an all-fiber in-line low noise delivery design using a fiber circulator, optical fiber, and fiber lens connected to a Grating-optic and reflective sensor chip.
