Webfront sensor (SHWFS). Di erent inverse l ters based on simple sensor models (i.e. the Hudgin or the Fried geometries) have been proposed so far [2]. In this work we have studied the applicability of these inverse l ters to the pyramid wavefront sensor. We wil l show that even using these simple mod- WebMy role is to advance the development of next-generation clinically relevant adaptive optics ocular imaging devices to allow early disease diagnosis and monitoring through a non-invasive visualization of subcellular structures in the eye.
