Because of the pixel number of charge-coupled device (CCD) camera, the field of view is limited to 1°. In order to have image of capillaries around vivo human fovea, we use mosaic method to obtain high resolution image in area of 6°×6°. Detailed structures of capillaries around fovea with resolution of 2.3 μm are clearly shown. Comparison shows that this method has a much higher resolution than current clinic retina imaging methods.展开更多
