The most common way to easure the density of the vaxis parts of a spray cloud is shine a beam of light
rough it using a laser transitter and record the reduced tensity due to the scatter and isorption. In its report Transittance analysis methods, the RRL describes improved ays of analysing and intereting such measurements id makes it possible to corntre results of earlier research help those developing new way suppresson equipment.
