Applications of fiber-based phase-sensitive optical low-coherence reflectometer

摘要

We describe a phase sensitive optical low coherence reflectometer using polarization maintaining optical fiber with high lateral, longitudinal and phase resolution for biomedical applications. The system utilizes three sample path configurations (i.e. single beam, lateral beams, and longitudinally delayed channels) and allows investigation of various topics in biomedical research. Applications include measurement of birefringence change, intensity and phase imaging, refractive index measurements, surface analysis, and measurement of solute concentrations.
