Abstract
Sensorless Adaptive Optics (SAO) allows easy integration of adaptive optics in retina imaging systems, however the iterative nature of the SAO optimization process requires long time to perform aberration correction and the inevitable subject motion during the optimization could compromise the AO correction. Here we present a multi-modal SAO retina imaging system that includes Optical Coherence Tomography (OCT), OCT-Angiography, confocal Scanning Laser Ophthalmoscopy (cSLO), and fluorescence detection. To mitigate the motion artifact and increase the SAO performance, we developed volumetric image tracking to extract merit function of SAO only within the region of interests.
