Computer-generated holography for optical trapping and imaging


Monika Ritsch-Marte

Division for Biomedical Physics, Medical University of Innsbruck, Austria


Wavefront shaping with spatial light modulators (SLMs) has become a powerful tool in Biophotonics. "Holographic optical tweezers" are a well-known and widespread tool. But an SLM can also be integrated into optical imaging systems, making the microscope programmable and customizable with respect to a given sample.  A particular strength of the Synthetic Holography approach with programmable phase masks is the possibility to multiplex, packing several things into one hologram. One can, for instance, take microscopic images that contain sub-images belonging to different imaging modalities, to different depths inside the sample, to different parameter settings, or to combine holographic imaging with trapping.


Monika Ritsch-Marte received her M.Sc. in Physics from the University of Innsbruck in 1984 and her PhD in Quantum Optics from the Waikato University in New Zealand (under the supervision of D.F. Walls) in 1988. After several PostDoc projects (Boulder/Colorado, Milano, Helsinki), and after completing her Habilitation at the Institute of Theoretical Physics in Innsbruck, she accepted the Chair of Biomedical Physics at the Medical University in Innsbruck in 1998 where she founded a Biomedical Optics group. Her current research interests include holographic optical tweezers, digital holographic microscopy and linear and non-linear Raman microscopy. She has received numerous research grants and awards, including an ERC Advanced Grant and the Boltzmann Award of the Austrian Physical Society. She is a member of the Austrian Academy of Science, of the German National Academy Leopoldina, and a Fellow of the Optical Society of America.
