Adaptive optics loop for en-face optical coherence tomography and laser scanning confocal microscopy

The capabilities of a novel deformable mirror and wave-front sensor combination to correct aberrations in microscopy are analyzed. The deformable mirror, (Mirao52-D, Imagine Eyes) is incorporated with a Shack-Hartmann sensor (HASO, Imagine Optic) within a complex imaging system able to produce simultaneous en-face Optical Coherence Tomography and Laser Scanning Confocal Microscopy images as well as B-scan OCT images. A large angle imaging along one of the scanning directions is demonstrated using the AO loop to correct for the interface optics aberration. The image is split into three panels, and each panel is imaged using its own set of corrections. The three images are subsequently collaged into a final image and preliminary promising results are presented.
