Professor Fercher is the recipient of the Royal Photographic Society’s 2014 Combined Royal Colleges Medal and is a pioneer in optical research. His work has led to a very important development in medicine called Optical Coherence Tomography. This is now a widely used imaging technique in medicine especially in eye examinations. By this method high resolution images of the front of the eye and of the retina can be obtained rapidly which enables the ophthalmologist to obtain valuable information such as the progress of glaucoma and other diseases. Other applications in medical investigation are emerging with this valuable technology, a tribute to the pioneering work carried out by Professor Fercher in Germany and Austria. Further developments are now being undertaken by research centres around the world, which is increasing the scope and performance of this exciting optical instrument.
