BS EN 13860 - 1:2003 Clarification

I have been reviewing standard BS EN 13869 - 1:2003 and have a query concerning Phase Linearity (Section 6.4.6).

In particular, the standard documentation states:

"The phase angle of the ith sample is to be compared with the theoretical value for the ith sample:

ÖIi = i.(fd/fe).360 + ÖOo.

My question is whether ÖOo should be ÖOi, i.e. comparing with the measured phase angle of the ith sample. If not what is ÖOo?

Apologies if I have missed something obvious.

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
