Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currently not possible. We also plan to make advances in the key area of scanning delay line technology by employing acousto-optics in OCT for the first time. Acousto-optics conveys advantages in no-moving-parts, scan-speed and accuracy.
