等差线和等倾线的计算机识别及绘制

在普通光弹仪上配置光电耦合二极管信号采集装置和专用程序计算机,就构成了能实时地处理光弹图象的系统。CCPD-1024成线阵排列,能同时采集模型中一个截面上的光强信号。等色线或等倾线条纹的位置由计算机从光强分布图上读出。CCPD-1024对模型扫描时,计算机记录了各个截面上的等色线和等倾线位置的信息,并据此绘制出反映全场性分布的光弹性条纹图案。

Recognition and Drawing of the Isochromatics and Isoclinics by A Computer

A general purpose polariscope provided wich a signal-collecting device made of Charge-coupled photodiodes and a specially programmed computer constitutes a system which can accomplish a real-time dispose of photoelastic images. Arranged in a line, CCPD-1024 is capable of a simultaneous collection of light intensity on a sectior of a model. And thus the fringe position of isochromatics or isoclinics can be read by the computer from the distribution diagram of light intensity, While CCPD is scanning to the model, the computer is recording the position of isochromatics and isoclinics on each section and drawing a fringe pattern which givesa full-field photoelastic image.
