Title: MEMS-based adaptive optics scanning laser ophthalmoscopy. Author: Zhang Y, Poonja S, Roorda A. Journal: Opt Lett; 2006 May 01; 31(9):1268-70. PubMed ID: 16642081. Abstract: We have developed a compact, robust adaptive optics (AO) scanning laser ophthalmoscope using a microelectromechanical (MEMS) deformable mirror (DM). Facilitated with a Shack-Hartmann wavefront sensor, the MEMS-DM-based AO operates a closed-loop modal wave aberration correction for the human eye and reduces wave aberrations in most eyes to below 0.1 microm rms. Lateral resolution is enhanced, and images reveal a clear cone mosaic near the foveal center. The significant increase in throughput allows for a confocal pinhole whose diameter is less than the Airy disc of the collection lens, thereby fully exploiting the axial resolution capabilities of the system.[Abstract] [Full Text] [Related] [New Search]
