you could check the following: Ql%B=vgKL
|f/Uzd ~
- if the surface/element tilt is too large T
"h jL
O #t[YP
- enough analysis rays used? QBG jH^kL
$ 7W5smW/
- have you used Coherent Data option under Detector setting. tRO=k34
^B%c3U$o
Someone above was right about that the non-sequential mode only uses geometric rays but you could see inteference fringes using Coherent Data.
