| Abstract: | The correction of human eye's aberration is one of the researching focuses in ophthalmology.It is of great importance to improve the visual performance of human eyes.The measurement of human eye's aberration is the foundation of the correction surgery.The paper studies the working principle of a subjective wave-front aberrometer and the key techniques of image sampling,image processing and analyzing,image segmentation with Ostu method and auto-tracing function.The self-produced aberrometer which used above key techniques can measure lower-order and higher-order aberrations accurately.The measure results can reach up to seventh order with 35 items.It will be widely used in the future. |
