Hi all.

I want to get the interference pattern of the beam homogenizer using lens arrays and focusing lens in Non-sequential mode. 

When we use the beam homogenizer, we can observe the interference pattern on the illuminated field easIly.

Gratefully, zemax offers an example file of the beam homogenizer which is illuminated by an ellipsoidal volume source.
(https://support.zemax.com/hc/en-us/articles/1500005489121-Fly-s-eye-arrays-for-uniform-illumination-in-digital-projector-optics)
However, in this example, the illuminated field is a very 'pretty' flat-top beam.

Of course, probably because it is assumed as a non-coherent beam.
If so, what if I want to simulate the beam homogenizing system with a real laser source that is coherent or partially coherent?
How can I get the interference pattern in this example? 

Thanks in advance.
