Adaptive optics (AO) is used for improving lateral resolution in opthalmic Optical-Coherence-Tomography (OCT) to correct for the aberrations in the human eye. AO works by measuring aberrations using a wavefront sensor and applying this information to the control of a deformable mirror in a closed loop, thereby compensating for the measured aberrations. This instrument combines the advantages of FD-OCT and advanced microtechnology for AO, using 35-element bimorph deformable mirror. AO system can effectively compensate low-order aberrations and maintain low rms wavefront error during closed-loop operations.
