  • Method for estimating the accuracy of an optical distance measuring probe
    Patent number: 6189365
    Abstract: 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.
