Macro-Scale OCT-on-a-Chip
A U.S. industry-academic collaboration, led by OSA Fellow James Fujimoto, Massachusetts Institute of Technology (MIT; USA), reports a proof-of-principle demonstration of cubic-meter volume optical coherence tomography (OCT). The researchers used advanced photonics integrated circuits (PICs) and MEMS technology to boost OCT performance on multiple scales over long ranges. Specifically, the team demonstrated 3-D subsurface tomographic imaging on a meter scale at a 100-kHz axial scan rate with 15-µm depth resolution ( Optica , doi: 10.1364/OPTICA.3.001496 ). OCT is a 3-D imaging technology commonly used in ophthalmology to get micron-scale images of small structures in the human eye ...
