【摘要】 为了检测瓷砖表面划痕,设计了使用单像素探测器的实验.实验采用特别的照度设计实现瓷砖表面面向探测器的辐射通量分布均匀化,实现均匀的检测灵敏度,并把划痕引起反射率分布异常转化为反射率累积异常(或者总辐射通量异常).研究了4种不同类型合格瓷砖各自的总辐射通量和划痕引起的总辐射通量异常,结果显示划痕导致总辐射通量的明显改变,证明该方法具有可行性.更多还原

【Abstract】 To detect the scratch on the ceramic tile surface,a detection experiment using a single pixel detector was designed.A special illumination design was used to realize the uniform radiation flux distribution on the ceramic tile surface and the uniform detection sensitivity,and the abnormal reflectivity distribution caused by the scratch was transformed into the cumulative reflectivity anomaly(or the total radiation flux anomaly).In the experiment,the total radiation flux of four different types of qualified ceramic tile and the abnormal total radiation flux caused by scratch were studied.The results showed that the total radiation flux changed significantly due to scratch.Therefore,the feasibility of this method was proved.更多还原
