Research on Fiber-Optic Optical Coherence Ranging System Based on Laser Frequency Scanning Interferometry

In this paper, a system for absolute distance measurement is proposed based on laser frequency scanning interferometry (FSI). The system utilizes a digitally tunable laser as the light source and employs synchronized pulses to drive an analog-to-digital converter (ADC) for interference signal acquis...
