Abstract

The challenge in producing a clear retinal image lies in the design of the imaging system that can reduce the strong aberrations of the human eye and the photographer's expertise in adjusting the fundus camera when the image is taken. A technique that combines an advanced adaptive optical system and image post-processing algorithm has been shown to be able to significantly improve the image quality up to 2-5 times higher resolution than currently used clinical devices [9]. The optical system has been designed to suppress low-order aberrations and enhance the precision of the wavefront measurement. Image post-processing mainly involves deconvolution by calculating the system transfer function (here the optical transfer function (OTF)) from the data obtained by the Shack-Hartman wavefront sensor.
