Basic Wavefront Aberration Theory for Optical Metrology
... The optical path difference (OPD) is defined as the difference between the aberrated and the ideal unaberrated wavefronts. The OPD is positive if the aberrated wavefront leads the ideal unaberrated wavefront as shown in Fig. 2. Also, if the aberrated wavefront curves in more than the unaberrated wav ...

In this paper we show that the concept of a NPS can be used more generally to partly compensate for aberrations of optical systems when we correctly choose the initial step heights and step widths of the NPS. Two different classes of aberration correction with such a NPS are studied. The first class ...
