Optical Tomography and Spectroscopy


The Optical Tomography and Spectroscopy (OTS) Topical Meeting builds on the strong foundations of the OSA Biomedical Optics Topical meeting where groundbreaking research on optical tomography and spectroscopy was historically discussed since mid-1990’s.

The 2020 meeting will focus on new developments in non-invasive optical tomography and spectroscopy, including the fields of diffuse optical tomography (DOT) and spectroscopy (DOS), diffuse correlation tomography (DCT) and spectroscopy (DCS), photoacoustic tomography (PAT), laser speckle imaging, Raman spectroscopy, fluorescence imaging, wavefront engineering to overcome scattering, as well as on novel biophotonics developments in pre-clinical and clinical applications. Such developments will also include a specific focus on diagnostic capabilities derived from probing tissues at the macroscopic level as well as development of portable and low cost instrumentation.

Example topics central to this meeting are novel instrumentation, data analysis algorithms, pre-clinical and clinical applications highlighting the validation and applicability of novel methods and concepts. This meeting is unique in the sense that it brings together researchers working at all levels of this multi-disciplinary effort and has historically been providing the echo-system that has been feeding other more specialized areas and applications. Optical coherence tomography, photoacoustics, diffuse correlation spectroscopy have all spun out of this meeting and now stand-alone application areas such as functional near-infrared spectroscopy of the brain emerged.
