Typical spec: 0.05 λ rms • For most diffraction limited systems, rms surface gives good figure of merit • Special systems require PSD spec • Geometric systems really need a slope spec, but this is uncommon. WebBFS is chosen at minimum Root Mean Square (RMS) irregularity2. Figure 1 shows a 2-D example of the relationship between ideal form and the actual surface.

Webvalley (PV) value and root-mean-square (RMS) value. In recent years, PSD is considered to be a more powerful way to characterize the super-smooth mirror surface [4, 13]. PSD is a mathematical quantity that defines the spectral content of the mirror surface. And a PSD analysis transforms a surface map into a spatial frequency representation. Weband extracted transient events, road segments with constant RMS values from the spatial acceleration data of road profile roughness. The road surface roughness spatial acceleration was described through nine classification parameters obtained through the statistical analysis of the road roughness data.
