  • Apparatus for high-speed surface relief measurement
    Patent number: 11231375
    Abstract: An apparatus for measurement of surface relief provides a phase sensitive camera and processing to reconstruct a wavefront profile matching the surface when illuminated with a known light source thereby providing noncontact surface relief measurements.
    Type: Grant
    Filed: May 20, 2019
    Date of Patent: January 25, 2022
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Soongyu Yi, Zongfu Yu
  • Wavefront detector
    Patent number: 11015982
    Abstract: A wavefront sensor system suitable for integration into an integrated circuit light detector may provide for wave angle sensors having varying functional relationships between the wave angle and signal to provide improved dynamic range. These wave angle sensors may be combined with integrated circuit phase angle sensors for a more complete analysis of the waveform.
    Type: Grant
