Paper Abstract

We use a deformable mirror (DM) in an adaptive optics dual channel optical coherence tomography/en-face eye fundus setup to control focus on the sample by adding aberrations to the wavefront. A program was created to sweep the equivalent focus created by the DM. Using this device we are able to sweep the focus between two extremes. This system is also used to measure and monitor any existing aberrations in the system, caused by the optical elements or the target object.
