  • Precise ranging system is of key importance in fields like multiple satellites flying formation, planets spatial positioning, shape measurements of large-scale structure, measurement of tiny displacement and measurement in commercial manufacture. For the advantages of fast measuring speed and high precision, the distance measurement technique with femtosecond optical frequency comb has become the focus of study in recent years. Based on a brief introduction of basic theory and main applications of femtosecond optical frequency comb, several distance measurements and results were given, including time-of-flight method, multi-wavelength method, dual combs method, spatial dispersive interferometry method, method based on real-time dispersive Fourier transformation and multi-technique method. The approaches of atmospheric refractive index correction and dispersion compensation were briefly introduced. A comparison and a summary of these methods were given and the latest progresses were introduced.

For the advantages of fast measuring speed and high precision, the distance measurement technique with femtosecond optical frequency comb has become the focus of study in recent years. Based on a brief introduction of basic theory and main applications of femtosecond optical frequency comb, several distance measurements and results were given, including time-of-flight method, multi-wavelength method, dual combs method, spatial dispersive interferometry method, method based on real-time dispersive Fourier transformation and multi-technique method. The approaches of atmospheric refractive index correction and dispersion compensation were briefly introduced. A comparison and a summary of these methods were given and the latest progresses were introduced.
