  • Surface Profiling by Frequency Domain Analysis of White Light Interferograms
    . 101-104 (1994). The fact that distances can be measured by observing how the interferometric phase changes. as a function of wavenumber has given rise to a wide variety of instruments variously described as. wavelength-shift interferometers, chirp laser radars, coherence radars, peak-fringe scanning...
  • Measuring Surface Slope Error on Precision Aspheres (.pdf)
    optics example ­ Interferometric reference mirror for NGST testing. A 0.5 meter diameter mirror was recently finished to better than 0.125 waves peak to valley at 632.8 nm over the 495.3. mm clear aperture. In addition to the surface figure requirement, the mirror has a slope requirement expressed...
