    FIGURE 1. The power spectral density (PSD) is created by taking a Fourier transform of the measured surface [1].
    Superpolished surfaces with sub-Angstrom surface roughness have become critical in cutting-edge optical systems, and this high level of precision requires specialized metrology...
