Instrumentation and Metrology

Quadriwave Lateral Shearing Interferometry Wavefront Sensors for Tomorrow’s Challenges in Optics Metrology

  • General description of the technology: Quadriwave Lateral Shearing Interferometry (QWLSI)
  • Advantages/Drawbacks compared to current metrology standard
  • Applications examples:
    • Beam metrology: free space optical communication
    • Optics metrology: wide angle lenses MTF measurements for consumer electronics and automotive industry, Transmitted Wavefront Error and Reflected Wavefront Error at optics design wavelength
    • Quantitative Phase imaging applied to refractive index change mapping in materials, laser-engraved waveguides
