A frequency-shifted feedback laser (FSFL), which generates a comb of chirped frequency components, has the ability for long distance and high accuracy optical ranging. In this report, the principles and performance of an FSFL ranging based on optical frequency-domain ranging are reviewed. This laser system could achieve a high accuracy, and less affected by distance up to range of 1 km. Applications of the FSFL to 3D shape measurement are also described.
