The influence of the finite sample spacing can be excluded
by inserting additional fibers. Their lengths must be
chosen so that they don’t coincide with multiples of the
distance sample spacing. For each combination, use the
total length of fiber to determine the distance offset error.
Finally, average all distance offset results.
Distance sampling error
The →distance uncertainty due to finite distance sample
spacing, expressed as ±half the span between the
maximum and minimum excursions from the straight line
model, in meters. Symbol:
∆L

. See Figure 3.
