Abstract

A MEMS deformable mirror has recently been employed in the AO system of an adaptive optics scanning laser ophthalmoscope (AOSLO). MEMS allows for a more compact, efficient and effective system. The AO system in the AOSLO operates with a modal closed loop. Aberrations after AO reduce the wave aberration to less than 0.1 microns RMS in most eyes. Results show improved resolution, brightness and contrast. Images of patches of retina show a well resolved cone photoreceptor mosaic as they change in size with eccentricities ranging from 0.6 degrees to 4.23 degrees from the fovea.
