Charge Coupled Device........
How does a charge Coupled Device (ccd) work?  I have been reasearching
this for a long time and have learned a lot.  I have even learned a 
little about potential wells, but I don't really understand what one
is yet.  Can anybody there help me?  Please don't tell me that, "A 
CCD works when a photon hits it.  The CCD then converts the photon
into an electrical impulse, depending on how much energy the photon 
had."  I know this already.  Thank you for your help.
