Abstract

一种批量钻石快速筛查方法，将待检钻石(6)放置在工作台(4)上，启动工作台(4)一侧设置的光源(1)，通过光源(1)对待检钻石(6)进行照射，此时照射光为含可见光的光谱，并通过成像装置(2)进行拍摄记录钻石分布位置，获得基础成像图；切换光源(1)，切换为含有波长180‑250nm的短波紫外线，光源(1)开启后再关闭，通过成像装置(2)进行拍摄记录发出磷光的钻石分布位置，获得磷光分布成像图；将基础成像图、磷光分布成像图进行对照，获得磷光对照图，通过图像识别技术在磷光对照图上标记出发出磷光的钻石，随后通过人工或者设备将发出磷光的异常钻石筛选出来。本筛查方法，检测速度快，且能同时对多颗钻石进行同时筛查，能够大幅提高检查效率，降低筛查成本。
