摘要
渐进多焦点镜片可为佩戴者提供自远点到近点全程、连续的清晰视觉。检测仪器由光源、聚焦镜、CCD、镜片夹具和转动装置等构成,用于检测渐变镜片视远区、视近区、渐变区的度数变化。提出了仪器装置的总体设计方案,通过CCD采集图像,经过后续处理可以得到镜片的屈光度分布图。结果表明,该仪器操作方便可行。
Progressive addition lenses can provide from far to near full, continuous and clear vision for the wearer. Detecting instrument consists of a light source, a focusing mirror, CCD, the lens clamp and rotating device. The equip- ment is used for the degree of change detection progressive addition lenses far zone, near zone, transition zone. A design scheme of instrument is put forward, image acquisition by CCD, after subsequent treatment can get lens power distribution map. The results show that the instrument is convenient and feasible operation.
