Hello all:

Is it possible to create a UDA on Image Plane such as shown below?

I am looking at an array of beams falling on the Image Plane, where each beam is to be coupled back into a given SM fiber. Basically I want to model the image plane as an array of SM fibers.

Problem: When I do a optimization on the rest of the system, the beam array can fall anywhere on the Image plane. Therefore, I would like it to restrict the array of beams falling on the Image plane with apertures as illustrated below.

Any ideas on how to do this is appreciated.
