I am working on the controls of a device that
includes a precision xy stage and a microscope
connected to a camera and a framegrabber.

I need to keep the camera focused onto a
region of the surface as the stage moves it
under the microscope.

I therefore need some type of autofocus.
I am contemplating a control loop that 
will maximize the high frequency content of
the area i want to focus on.

Does anyone have any similar experience?
Are there any relevant publications to look
for?

Thanks
