Description
- Abstract
- 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.
