A new interferometry method uses a frequency-comb light source for surface profilometry. This technique accurately measures surface profiles and step heights on discontinuous objects without mechanical scanning.

Area of Science:

  • Optics and Photonics
  • Metrology
  • Surface Science

Background:

  • Traditional surface profilometry often requires mechanical scanning, limiting speed and applicability to continuous surfaces.
  • Discontinuous objects present challenges for accurate surface measurement using conventional interferometric techniques.

Purpose of the Study:

  • To propose and demonstrate a novel interferometry technique for surface profilometry and tomography of discontinuous objects.
  • To enable non-contact, high-accuracy surface measurements without mechanical scanning.

Main Methods:

  • Utilizing a frequency-comb light source for interferometric measurements.
  • Implementing a surface profile measurement scheme by sweeping the comb interval frequency.
  • Applying the technique to measure step heights on discontinuous surfaces.
