摘要
通过对具备校准功能的黑白密度计的校准算法进行复现,阐明了黑白密度计校准后测量其他标准密度片误差超差的原因,并借助Matlab数学软件对算法存在的问题进行了分析,对黑白密度计的制造使用提供了参考与借鉴。
By reproducing the calibration algorithm of the black-and-white densitometer with calibration function,this paper expounds the causes of the error out of tolerance in measuring other standard density films after calibration of the black-and-white densitometer,and analyzes the problems existing in the algorithm with the help of Matlab mathematical software,which provides reference for the manufacture and use of the black-and-white densitometer.
