| Abstract(in English) | Since many naturally occurring surfaces have Gaussian height distribution, physical characteristics of them can be described by two kinds of roughness parameters alone, the root-mean-square (rms) height and correlation length. When we accurately estimate these parameters from measured surface height-profile, data samples with sufficiently long record length are required. However, the criterion of the data length required for accurate estimation of the parameters is not clear. In this report, we statistically estimate the error arising from the data length and check the results through a Monte Carlo simulation. From this analysis, we can confirm that for estimation of the rms height and correlation length with a precision of 10%, data lengths of 240lc and 270lc are required, respectively, where lc is the true value of the correlation length. |
