title: Spectrally encoded confocal scanning laser ophthalmoscopy.
abstract: We present in vivo human fundus imaging using a fiber-based confocal scanning laser ophthalmoscope (SLO). Spectrally encoded confocal scanning laser ophthalmoscopy (SECSLO) utilizes a spectral encoding technique in one dimension, combined with single-axis lateral scanning, to create video-rate reflectivity maps of the fundus. This implementation of the SLO allows for high-contrast high-resolution in vivo human retinal imaging through a single-mode optical fiber. We experimentally quantify the full confocality of SECSLO in both the spectrally encoded and laterally scanned dimensions, and demonstrate 50 Hz frame rate fundus imaging.
