Diagonal Slice Spectrum Analysis of Rough Surface Profile

Li Chenggui Beihang University, Beijing, 100083  
Bispectrum is an available method to describe quadratic phase coupling, non-linearity and non-symmetry of stochastic signal, whereas its shortcomings are also obvious, such as complex computation, lower estimating exactness, not convenient vision. In this paper, an improved method, diagonal slice spectrum analysis, is presented and used to characterize the asymmetry and coupling of the rough surface. The experimental results show that the diagonal slice spectrum analysis technique is simple, effective and reasonable, and that it is possible to explain the changes of surface roughness spacing and amplitude parameter.
