Extraordinary Dispersion Engineering in Enabling Ultrafast Swept Source Visiblelight Optical Coherence Tomography - Project Summary This Sbir Phase 1 Project Focuses on Developing, Characterizing, and Validating a New Swept-source Laser System to Enable the Next-generation Clinical Visible-light Optical Coherence Tomography (vis-oct). We Will Develop a Novel Design of Photonic Bandgap Fiber That Comprises Fiber Bragg Grating Array to Temporally Disperse Broadband Picosecond-pulses to Create a Wavelength Sweeping Pulse Train. the New Swept Source Can Operate Up to Tens of MHZ Frequencies Without Mechanical Moving Parts, Enabling Ultra-high-speed Swept-source Vis-oct (ss-vis-oct) for the First Time. the New Light Source Will Also Enable Truly Shot-noise-limited Performance in Vis-oct While Mitigating the Artifacts Caused by Both Eye Motions and Fringe Washout. During the Project Period, We Will Design, Fabricate, and Optimize the New Swept-source Laser to Achieve the Desired Sweeping Frequency, Bandwidth, and Phase Stability. We Will Further Develop a Prototype Ss-vis-oct and Fully Test Its Performance in Phantom Eyeballs, Ex Vivo Bovine Eyes, and Blood Vessel Phantoms.
