Adaptive optics (AO) has been proved as a powerful means for high resolution imaging of human retina. Because of the pixel number of charge-coupled device (CCD) camera, the field of view is limited to 1 deg.. In order to have image of capillaries around vivo human fovea, we use mosaic method to obtain high resolution image in area of 6deg.*6deg.. Detailed structures of capillaries around fovea with resolution of 2.3 ?m are clearly shown. Comparison shows that this method has a much higher resolution than current clinic retina imaging methods.
