Paper Abstract

Recently a new method of retinal imaging by laser scanning ophthalmoscopy was developed that overcomes the intensity problem of conventional fundus photography and promises further advantages. The laser scanning ophthal-moscope has been modified by incorporating an adaptive optical feedback system for laser beam control. For wave-front reconstruction maximum likelihood methods and the Gerchberg-Saxton-algorithm are applied. The system essentially provides an elimination of optical eye aberrations which diminish the fundus image quality. On the other hand by active focus control and/or wavefront sensing the aberrations of the human eye like astigmatism of the cornea and spherical aberration of the lens can be measured.
