基于CCD与单片机技术的自动焦度仪
The Auto-diopometer Based on CCD and Single-chip Technologies
摘要
Abstract
Currently,the focusing-image visual dioptometer is used to measure the lens vertex power(D). The defocus error is generated as a result that the post-vertex of the eyeglasses is not superimposed with the post-focus of the objective of the dioptometer because the eyeglasses do not have the same post-surface curvature. So the measuring errors is too large (when D>15 m-1) and lenses are not qualified. The measuring principle and error source of the focusing-image visual dioptometer was analyzed in this paper. An auto-diopometer based on CCD and single-chip technologies was designed and the method of auto-correcting the defocus error was investigated paper. The new auto-diopometer realized auto- measuring of the lens vertex power (D) with improved measuring precision.关键词
