Adaptive optics retinal scanner for one-micrometer light source
We developed an adaptive optics (AO) retinal scanner by using a light source with a center wavelength of 1-um. In a recent study on optical coherence tomography (OCT), it was proved that 1-um 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 μm. We ...
