为了实现对用于校准能见度仪的标准散射体的快速准确定标,通过测量标准散射体不同散射角的散射系数,实现对标准散射体不同散射角所模拟的大气能见度进行准确定标并对定标系统进行校准.根据定标系统的组成与工作原理,确定定标系统的校准方法并建立相应的校准链,并设计校准链的各组成部分的校准方法.通过对已知散射系数的标准散射体进行定标,验证校准后定标系统定标结果的准确性,进而验证了定标系统校准方法的正确性.实验结果证明:定标系统对标准散射体的散射系数定标结果的误差为7.93%;经由定标系统定标的标准散射体所模拟的大气能见度的最大误差为8.61%,满足用于校准能见度仪的标准散射体的使用要求.

Calibration Method for Standard Scattering Plate Calibration System Used in Calibrating Visibility Meter

In order to realized the rapid and accurate calibrating of the standard scattering plate uesd in calibrating visibility meter,calibrateing the simulated atmospheric visibility by measuring the scattering coefficient of multiple scattering angle of the standard scattering plate,and the calibration system was calibrated.According to the composition and working principle of the calibration system,the calibration method was determined,the calibration chain of the calibration system was established,and the calibration method for each step of the the calibration chain was designed.By calibrating the standard scattering plate with a given scattering coefficient,the veracity of the calibration result of the calibration system and the correctness of the calibration method were verified.The experimental results prove that the error of the calibration results of scattering coefficient of standard scattering plate is 7.93 ％0,the error of the simulating visibility of the standard scatting plate calibrated by the calibration system is 8.61％,satisfied the requirements of the standard scattering plate used in calibrating visibility meter.
