you could check the following: bHcb+TR3
xkR--/f
- if the surface/element tilt is too large H=]$9ZH!

- enough analysis rays used? uEQH6~\{Nl

- have you used Coherent Data option under Detector setting. h.c<A{[I6c

Someone above was right about that the non-sequential mode only uses geometric rays but you could see inteference fringes using Coherent Data.
