Projeto de um sistema de ótica adaptativa para diagnósticos de aberrações monocromáticas oculares

Abstract

To determine the extent and severity of eye diseases, medicine makes use of tests that allow diagnosis through images of the fundus of the human eye. In order for the analysis of a disease to be done efficiently, it’s necessary that the generated image does not present deformities. However, because isn’t an ideal system, the eyeball has some intrinsic defects, such as monochromatic aberrations that distort the image generated in the examination. The objective of this work was the planning of the minimum requirements for an apparatus capable of correcting ocular monochromatic aberrations through an adaptive optics system applied to ophthalmology. The project was composed of a market research encompassing the optical and electrical materials that make up the system as wavefront sensor, deformable mirror, scientific camera, among others. In addition, it was determined that the control method to be used to generate a sharp image is the tilt method, because it is the most direct and flexible for the correction of the aberrated wavefront. Finally, the economic analysis presented the best costbenefit according to the Brazilian reality.
