How to Create a Perfect Microscope by Adding a Computer
Changhuei Yang, Professor of Electrical Engineering, Bioengineering and Medical Engineering, Caltech,

Microscopes are complex and fussy creatures that are capable of delivering very limited image information. This is because physical optical lenses are intrinsically imperfect. The perfect lenses we draw in high school ray diagrams simply do not exist.  In this talk, I will discuss our recent work on Fourier Ptychographic Microscopy - a computational microscopy method that enables a standard microscope to push past its physical optical limitations to provide gigapixel imaging ability. This transformative way of performing microscope only requires a low-end microscope, a marquee sign fragment, some legos and a muscular computer.
