摘　　要：A compact line scanning quasi-confocal ophthalmoscope （LSO） is presented in this letter. Compared with a conventional scanning laser ophthalmoscope （SLO）, the bench-top LSO significantly reduces the size, complexity, and cost of SLO utility with routine use. The LSO uses one moving part to produce high-contrast and high-resolution quasi-confocal images with nearly the same performance as a SLO. The LSO has a moderate field of view （～10°）, which enables images of the macula, tile optic nerve head, and other targets to be obtained more quickly and efficiently. An image of the optic： nerve head is taken in a preliminary investigation on human subjects. Individual nerve fiber bundles and vessels are resolved at a shallow depth, with a lateral resolution of nearly 10 μm.A compact line scanning quasi-confocal ophthalmoscope （LSO） is presented in this letter.
