Hybrid LSLO/SDOCT retinal imager

摘要

In this paper we demonstrate the integration of two technologies, Line-Scanning Laser Ophthalmoscopy (LSLO) and Spectral Domain Optical Coherence Tomography (SDOCT) into a single compact instrument that shares the same imaging optics and line scan camera for both LSLO and OCT imaging. Co-registered high contrast wide-field en face retinal LSLO and SDOCT images are obtained non-mydriatically with less than 600 microwatts of broadband illumination at 15 frames/sec. The hybrid instrument can work in three different modes: LSLO mode, SDOCT mode, and LSLO/SDOCT interleaved mode. This instrument could be useful in clinical ophthalmic diagnostics and emergency medicine.
