Optical Tomography and Spectroscopy

20 April 2020 – 23 April 2020 OSA Virtual Event - Eastern Time (US & Canada) (UTC - 05:00)

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.



  1. Diffuse optics (DOT/DOS, DCT/DCS)
    Covering all salient aspects ranging from algorithms and devices to pre-clinical and clinical applications. 
  2. Laser speckle imaging
     Broadly, this area covers the use of laser speckles and their statistics for biomedical imaging and monitoring.
  3. Photoacoustic tomography
     Covering all salient aspects ranging from algorithms and devices topre-clinical and clinical applications.
  4. Raman spectroscopy & Fluorescence imaging
    These emerging new areas are represented  at all levels from the physical basis to novel new devices to pre-clinical and clinical applications.
  5. The future
    Novel developments for pre-clinical and clinical applications covering a wide range of methods.
