  • Title: High Speed 3D Optical Coherence Tomography Imaging
  • Abstract: Optical coherence tomography (OCT) has attracted much attention after it was introduced in the 1990s [1]. This cross-sectional imaging technique may provide depth-resolved information of bio-tissues with micron-scale resolution in a non-invasive manner and therefore has been widely used in clinic. Nowadays, there is an increasing need for real-time volumetric imaging in OCT-based clinical diagnosis. To realize real time 3D optical coherence tomography imaging, there are several challenges in optical source, detection scheme, data processing and etc., due to the acquisition and processing of massive data of >1GB/s required by real time 3D display. In this talk, I will discuss and demonstrate some new progress on the solutions related to these challenges. It proves that linear-in-wavenumber swept laser and all-optical 40MHz swept-source as the optical source, and compressed sensing and time serial optical computing play important roles to achieve high 3D optical coherence tomography imaging.
