Adaptive optics in ophthalmology: human eye wavefront generator

摘要

We present human eye wavefront generator (HEWG) introduced inside aberrometer for dynamic reproduction of human eye aberrations. It's main element is bimorph deformable mirror and a telescope. Deformable mirror generates human eye aberrations in real time. We have recorded aberrations time traces for plurality of subjects using aberrometer and reproduced them with the help of the generator at 10Hz frequency, that is inherit to human eye aberrations dynamics. Experimental results indicate that HEWG can reproduce dynamics of human eye aberrations with residual error less than λ/10 microns. Such a model can be useful for testing, for example, customized contact lenses or wavefront guided aberrometers.
