| 摘 要： | 基于后向测量法设计了线材直径测量系统,用2片光电池分别测量光源光强和信号光强,经过适当处理后做除法运算,可较好地消除光源光强波动的影响．利用光电池的积分效应能克服线材表面各处反射率不同的影响．在线材直径为1～6 mm时,实验结果的最大相对误差为1．1％．

| Abstract: | Using two photocells to measure the intensity of source light and signal light, divide operation is done after some processing of the photocell signals to eliminate the influence of the instability of the source light radiator. The influence of the fluctuating reflective ratio of the wire rod can be reduced by the integral effect of photocell. The maximum relative error is 1. 1 percent while the wire rod diameter is in the range from 1 mm to 6 mm in experiment. |
