Optical coherence tomography (OCT) is capable of high-resolution cross-sectional imaging of retinal tissue and is typically paired with near-infrared (NIR) wavelengths due to its ability to penetrate deeper into tissue compared to visible wavelengths. This imaging modality has helped ophthalmologists diagnose and learn more about the structural changes found in retinal diseases. To help further the effectiveness and versatility of this imaging modality, broadband visible wavelengths were incorporated into the system to enable detection of spectroscopic signals. Wavelengths centered at 580 nm will provide valuable molecular information that was not provided with just NIR wavelengths. Here we demonstrated the use of visible wavelengths and introduced a novel spectroscopic analysis technique in a visible OCT system, which was then characterized and tested.
