基于激光腔增强技术的前向散射能见度仪校准方法研究
|
摘要
为了填补前向散射能见度仪校准的空白,利用激光腔增强技术,搭建了一套开放式能见度校准系统,通过在能见度模拟舱中用气溶胶发生器产生单分散硬脂酸气溶胶颗粒产生模拟能见度环境,实现前向散射能见度仪的校准。与前向散射能见度仪、透射式能见度仪分别在小型模拟舱((长2m×宽1m×高1m))和大型模拟舱(长20m×宽3.5m×高3m)中开展了比对实验,实验结果表明,在100～2000 m能见度范围内,与透射式能见度仪的相对误差在5%以内,与前向散射能见度仪的相对误差在10%以内,均具有较好的一致性。这套系统可以用在较小的小型能见度模拟舱中,为前向散射能见度仪的实验室校准提供可行的技术手段。
In order to make up the shortage of calibration of visibility meter,built a suit of open path visibility calibration system device based on laser cavity enhanced technique.The calibration of the forward scattering visibility meter is achieved by simulating the visibility environment in the visibility simulation chamber,with monodispersed stearic acid particulate matters generated by aerosol generator.Contrast tests were taken with forward-scattered visibility meter in a small simulation chamber(length 2 m×width 1 m×height 1 m)and transmission meter in large simulation chamber(length 20 m×width 2.5 m×height 3 m).The results shows,within the visibility of 100～2000 m,the relative error with transmission visibility meter is less than 5%,and the relative error with forward-scattered visibility meter is less than 10%,and both of them show a good consistency.This system can be used in a smaller visibility simulation chamber,and provide a feasible technique method for laboratory calibration of forward-scattered visility meter.
