Microscope on cellphone

You may remember when I wrote about how cellphones could be used as microscopes in dermatology and I also mentioned the iMicroscope once. Now over at Spoonful of Medicine, a new cheap device is described:

Aydogan Ozcan is a professor of electrical engineering at UCLA. From $10 worth of parts, he built an apparatus that turns a cell phone into a mobile microscope. His device contains no lens, instead relying on a system of electronic magnification that creates a hologram, which is then transmitted wirelessly to a lab. The cellphone microscope could help doctors working in remote areas rapidly analyze patient blood samples, allowing them to screen for diseases like malaria, TB and anemia.
