Paper Abstract

In considering of the two boundary conditions arising in a fringe-counting interferometer(FCI): the non-zero original optical path difference(OPD) between reference and measurement arms; and the zeroed interference order corresponding to the original OPD at the begining of measurement, an amended length measurement formula and its whole-error distribution equation are derived, on which the concept of optical-origin drift(OOD) iS introduced. The effect of OOD on the measurement accuracy and the geometric design of interferometers is discussed in detail. Practical examples are also presented.
