. The question was
would this display provide useful information beyond the traditional alpha
numeric info.

The trend with Rb clocks is to try and make then smaller and cheaper.
If all you need to do is detect the amount of light a one-pixel sensor
is enough. If you divide the sensor into multiple pixels you just get
more noise because fewer photons fall on each pixel. So a
photo-transisor is ideal as
Hmm in interesting prospect. However its unclear to me as to the benefit of
trying this. I do know what gets lost. Its not just a dimming of the light
1-2% as stated its also the modulation on the light beam. I think 286 Hz
thats critical to locking the system.
So the ccd is very capable of recover
