Abstract

We demonstrate for the first time the integration of two technologies, Spectral Domain Optical Coherence Tomography (SDOCT) and Line-Scanning Laser Ophthalmoscopy (LSLO) into a single compact instrument that shares the same imaging optics and line scan camera for both OCT and LSLO 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 LSLO/SDOCT hybrid instrument could have important applications in clinical ophthalmic diagnostics and emergency medicine.
