From Ocular Biometry to Cellular Resolution – and Multifunctional OCT – Coherence Ranging and Imaging in the Human Eye over 35 Years
In the mid 1980s, first applications of low coherence interferometry (LCI) to tissue metrology and analysis were reported. Starting from one-dimensional ocular biometry, the technology has evolved into a high-speed, 3-dimensional imaging technology, now known as optical coherence tomography (OCT), with a multitude of functional extensions that has revolutionized ocular diagnostics. This talk illustrates the evolution of the technology over a third of a century, as seen from a Viennese perspective. Starting with first axial eye length measurements by LCI, a bridge is spanned to modern high-speed, high-resolution, and multifunctional OCT, including some examples of current research in the OCT labs at Medical University of Vienna.
Christoph K. Hitzenberger is Professor of Medical Physics and Vice Chair of the Center for Medical Physics and Biomedical Engineering, Medical University of Vienna, and Editor-in-Chief of Biomedical Optics Express. He works in Biomedical Optics since 1987 and is one of the pioneers of low coherence ocular biometry and optical coherence tomography. Among his most important contributions to these fields were the introduction of the optical A-scan in 1990, the first demonstration of Fourier domain OCT methods in 1995, and pioneering work in polarization sensitive OCT since 2000. He is Fellow of OSA and of SPIE; his pioneering contributions to OCT were awarded with the Russ Prize of the US National Academy of Engineering in 2017 and with the Austrian Cross of Honour for Science and Art, First Class.
