Slightly off-topic from the original question, but related: is there a
reason why you split the channels at the Fourier plane of your 4f
system? I can imagine that there may be advantages to placing the
dichroic elsewhere in the infinity space, such as immediately before the
Fourier plane. This should essentially give you two independent copies
of the pupil (one for each camera).

I am just curious whether there is an optimum position of the dichroic
for minimizing the aberrations imparted on the split images.

Cheers,
Kyle
