Hello everyone.

I am interested in optimizing an optical system that contains a micro-lens array. 

I am aware of the user defined surface type and the "US_ARRAY.C" objects. I understand that this would help me build the optical system, but now I am interested in optimization. Since the MLA will generate multiple spots/wavefronts, how can I include this information into the Merit function?

Also, in order to diagnose the performance of the system I would like to know the MTF for each lenslet. Is it possible to build an analysis plot that only considers rays from a specific region of the image?

Thanks very much in advanced for any help.

John.
