Area of Science:

  • Optics and Photonics
  • Metrology
  • Laser Interferometry

Background:

  • Short-range absolute distance measurement using dispersive interferometry is limited by an unmeasurable dead-zone near zero-position.
  • Femtosecond laser-based dispersive interferometers face challenges in minimizing this dead-zone, critical for millimeter-order precision.

Purpose of the Study:

  • To propose novel data processing algorithms for dispersive interferometry to shorten the dead-zone.
  • To enhance measurement accuracy in short-range absolute distance applications.

Main Methods:

  • Development of a spectral fringe algorithm and a combined algorithm (spectral fringe + excess fraction method).
  • Simulation of proposed algorithms to assess dead-zone shortening and accuracy.
  • Experimental validation using a constructed dispersive interferometer setup.

Main Results:

  • The proposed algorithms effectively shorten the unmeasurable dead-zone.
  • The dead-zone was reduced to half the size compared to conventional methods.
  • The combined algorithm demonstrated further improvements in measurement accuracy.

Conclusions:

  • The spectral fringe and combined algorithms offer a viable solution for minimizing the dead-zone in femtosecond laser dispersive interferometry.
  • These algorithms enhance precision for millimeter-order short-range absolute distance measurements.
  • The combined algorithm provides superior accuracy, making it suitable for demanding metrology applications.
