Binocular Adaptive Optics Vision Simulator

The retinal image quality of the human eye is degraded by ocular aberrations (see Spatial Vision for more information). Our binocular adaptive optics (AO) vision simulator is a powerful tool to understand the roll and impact of the higher-order aberration on vision (Sabesan et al. 2007).

The AO Vision simulator is a noninvasive system which permits to correct the aberrations of the eye and induce new ones in real time. In the next image we can see a schematic figure of the system. Using a wavefront sensor, we measure the aberrations of the eye. This wavefront sensor is connected to a deformable mirror located in the pupil plane. Modifying the mirror's surface we can modify the wavefront, so the subject perceives the stimulus under the optical condition that we want to study. Our binocular AO vision simulator has two identical monocular AO channels, which allows correcting or modifying the aberrations in both eyes independently.
