Abstract Details

2016, Master of Science (M.S.), University of Dayton, Electro-Optics.
Adaptive optics (AO) is a technology used to sharpen images through real time compensation of optical aberrations. The adaptive optics was firstly used in astronomical telescopes. Now this technique is widely adopted in fields encompassing physics, chemistry, electronics, and computer science. Particularly in vision science, adaptive optics can compensate the aberrations in the eye such that the information of a diseased eye can be read easily. Though the adaptive optics technology is relatively young, it has been demonstrated for advanced ophthalmoscopy as well as for vision test. In this thesis, a commercially available adaptive optics system was assembled up and tested firstly. Then the adaptive optics system was modified to test an eye model. The eye model consists of a lens and a movable mirror, which can simulate different types of diseased eyes by changing the distance between the mirror and the lens. The diseased eye model introduced aberrations to the system, and the deformable mirror in the adaptive optics system was activated and changed the shape to compensate the aberrations. But the correction range by the deformable mirror is limited. By testing the simple eye model, the working range of the deformable mirror and the wavefront sensor were characterized and determined.
