Abstract
Visible light OCT requires light sources with high spatial brightness and broad spectral range. Typical solutions are based on supercontinuum generation from a short pulse. Here, we demonstrate visible light superluminescent diodes (SLDs) for OCT imaging of the human retina. SLDs are about an order-of-magnitude less costly than supercontinuum sources and have lower intrinsic excess noise, enabling imaging closer to the shot noise limit. We show that while SLDs lack continuous broadband spectra, they can provide concentrated power at specific wavelengths. Our approach enables us to image near the shot noise limit in vivo and provides novel chromophore information.
