摘要：

We have developed a compact, multimodal instrument for simultaneous acquisition of en. face quasi-confocal fundus images and adaptive-optics (AO) spectral-domain optical coherence tomography (SDOCT) cross-sectional images. The optical system including all AO and SDOCT components occupies a 60 x 60 cm breadboard that can be readily transported for clinical applications. The AO component combines a Hartmann-Shack wavefront sensor and a microelectromechanical systems-based deformable mirror to sense and correct ocular aperrations at 15 Hz with a maximum stroke of 4 mu m. A broadband superluminescent diode source provides 4 mu m depth resolution for SDOCT imaging. In human volunteer testing, we observed up to an 8 dB increase in OCT signal and a corresponding lateral resolution of < 10 mu m as a result of AO correction. (c) 2007 Optical Society of America.
