We developed an adaptive optics (AO) retinal scanner by using a light source with a center wavelength of 1-mu m. In a recent study on optical coherence tomography (OCT), it was proved that 1-mu m light provided higher image contrast of deep region of the eye than 840-nm light. Further, high lateral resolution retinal images were obtained with AO. In this study, we performed measurements on two normal subjects in the AO-SLO mode and analyzed its performance toward developing the AO-OCT. With AO correction, we found that the residual RMS wavefront error of ocular aberration was less than 0.1 mu m. We also found that the AO retinal scanner in the AO-SLO mode enabled enhanced observation of photoreceptor mosaic.
