you could check the following: >>%E?'9A
9w dl1QS
- if the surface/element tilt is too large Dbw{E:pq
mOfTq]
@B
- enough analysis rays used? PnZY%+[I
jJyS^*.X
- have you used Coherent Data option under Detector setting. d8.A8<wUr
0+Z?9$a1
Someone above was right about that the non-sequential mode only uses geometric rays but you could see inteference fringes using Coherent Data.
