FSU Microscopy Primer

Florida State University hosts a terrific Microscopy Primer, including a whole section on Virtual Microscopy. They have lots of little Java-based tutorials to demonstrate various types of microscopy. The section on Digital Imaging is wonderful. They don't [yet] explain the advantages of line scan cameras over 2D CCD arrays, but I'm sure they will :)

The site also features a cool Microscopy Museum. It is interesting to see how much has changed in 400 years - and how much hasn't...

Anyway it is a terrific resource, if you're interested in Virtual Microscopy, you'll find it very informative.
