Abstract

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 2m×width 1m×height 1m)and transmission meter in large simulation chamber (length 20m×width 2.5m×height 3m).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.
