Compact Powell-Lens-Based Low-Coherence Correlation Interrogation System for Fiber-Optic Fabry-Perot Sensors
For the absolute cavity length interrogation of fiber-optic Fabry-Perot (FP) sensors, a low-coherence interferometer based on the Powell lens is proposed and demonstrated. The usage of a large-fan-angle Powell lens combined with a tiny fiber collimator for achieving a line-type beam and uniform beam...
