After working on the mathematics, computational analysis and design
of his
device, Dr Wang personally constructed his full - size, ready - to - test
prototype (
pictured right)-- a demonstration
of practical engineering skills that impressed his supervisor Professor Ball.
«The
device is currently just a
prototype, but it shows that it is possible to build a cheap camera capable
of taking quality
pictures of the retina without dilating eye drops,» Shen said.
