CORRECTING OCULAR ABBERATIONS IN OPTICALCOHERANCE TOMOGRAPHY

摘要

The theoretical confocal profile of an ideal Optical Coherence Tomography (OCT)system is modeled and analyzed. The results of the analysis are used to determine thesuitability of both Time Domain (TD-OCT) and Fourier Domain OCT (FD-OCT) inconjunction with Adaptive Optics. It is shown that for large depth ranges the interferencesignal from FD-OCT drops below the level of TD-OCT interference signal indicating thatfor larger depth ranges, TD-OCT is a more suitable system. A TD-OCT novel systemdesign is presented as well. The system incorporates a high stroke deformable mirror(MIRAO52 Imagine Eyes) and a Shack-Hartmann wave-front sensor. It is able toproduce simultaneous en-face OCT and Scanning Laser Ophthalmoscopy (SW) retinalimages as well as OCT longitudinal images.
