This study introduces a new fluorescence detection method to analyze laser-modified metal surfaces. It complements traditional reflectance techniques for detailed surface topography characterization.

Area of Science:

  • Materials Science
  • Surface Science
  • Optical Metrology

Background:

  • Characterizing complex surface topographies, especially in tilted and corrugated areas, is crucial for material analysis.
  • Traditional video-confocal profilometry effectively analyzes reflecting and non-reflecting surfaces.
  • Laser irradiation significantly modifies metal surfaces, necessitating advanced characterization methods.

Purpose of the Study:

  • To develop and evaluate an alternative fluorescence detection method for characterizing metal surfaces.
  • To compare the effectiveness of fluorescence-based techniques with traditional reflectance methods.
  • To obtain combined surface topography representations using both signal types.

Main Methods:

  • Utilized video-confocal profilometry for surface characterization.
