Method for estimating the accuracy of an optical distance measuring probe |
摘要 |
A method for estimating the error of a measured shape of a workpiece, as measured using an optical probe. A series of N equally spaced distance measurements are transformed to a power spectrum. The average power above a cutoff index is divided by N to give an estimate of the variance of the shape measurement.
