Determination of scanner angular oscillation relative to scale of position measurement unit, records angular positions, to obtain a measure of the variation over time |
摘要 |
The variation of angular position (W2, D2) of the scanning unit (2) is recorded, to determine a measure (DE; D2, W2) of its course over time. An Independent claim is included for the corresponding measurement unit.
