HKU's Department of Earth Sciences: new laser-induced fluorescence techniques uncover never-before-seen details in fossils

Dr. Michael Pittman of HKU together with eight international colleagues have developed a simple new technique to analyse fossils. Published in the open-access journal "PLOS ONE", the technique, called laser-stimulated fluorescence (LSF), utilises lasers to stimulate fluorescence in fossils that normally don't fluoresce under standard UV lighting, with the new view photographed through a camera lens.
