Abstract (en)
[origin: WO2011022803A1] A system and method for fundus imaging are provided wherein selective illumination of a sector, e.g. a half, of the field of view of the fundus, using off-axis illumination, provides images of acceptable clarity, resolution, and size, with significantly reduced reflections, in a compact system. By rotating illumination around the optical axis, other sectors of the fundus may be selectively and sequentially illuminated, and a combined image of the entire field of view of the fundus may be obtained by combining images, e.g. Two or more half images, obtained within a single shutter exposure period during which the light source is flashed at two or more positions. In particular, an illumination system using LED light sources and a rotatable occluder provides for a lightweight, handheld and portable fundus imaging system, which may take the form of a fundus camera, a fundus imaging lens module for regular camera, or an adapter which couples to the standard lens of a camera to create a low cost fundus camera.
