AbstractA compact, high-speed line scanning quasi-confocal ophthalmoscope (LSO) for retina imaging is presented in this paper. By using a line beam to illuminate the retina, meanwhile a linear array sensor is used for imaging the retina, the LSO system significantly reduces the size, complexity, and cost comparing to a conventional confocal scanning laser ophthalmoscope (CSLO). With only one moving scanner to provide raster scanning of the line beam of the retina, the imaging frequency achieves 160 Hz and the lateral resolution is nearly 10 μm for 1024×330 pixels imaging mode. Preliminary experiments are performed for imaging the macula, the optic nerve head and other targets, providing high resolution and high speed videos of human retina. © 2014 SPIE.; A compact, high-speed line scanning quasi-confocal ophthalmoscope (LSO) for retina imaging is presented in this paper.
