摘要
Tracing of a random profile with a mechanical profiler with a spherical tipped stylus has been investigated by means of computer simulation. It is shown that the fractional measuring errors of mis roughness depend on only the ratio of rms roughness CT to the stylus tip radius r and the ratio of rms roughness to the 1/e correlation length ρc. The ratios σ/r were in the range of 0.005-0.05 and the ratios σ-/ρcwere equal to 0.028 and 0.048. © 1997 Optical Society of America.
