It measures contrast, which, as in the MTF tables, relates to sharpness
and therefore focus. I am not familiar with the Sinar focus assist.

When I saw Stuart at Robert White a few months ago, there was a one
point system, but he said that, about now, they were going to introduce
the simultaneous three point system, so you can select any three points
in any plane and simultaneously get numerical values for the sharpness
of all three points - Ideal for setting up a view/monorail camera (like
a Sinar)

For use with a Sinar yaw-free monorail you would try to find points on
the yaw-free axes to focus on.

It would be possible to design a semi-robotic camera that would
tilt/swing about any axis, and automatically put the plane of sharpest
focus through those points... it would be nice to make it a PhD project!
