SCANNING RADIOMETER FOR MEASUREMENT OF FORWARD-SCATTERED LIGHT TO DETERMINE MEAN DIAMETER OF SPRAY PARTICLES

摘要

A scanning radiometer was built that measures forward-scattered light to determine the mean diameter of spray particles. An optical scanning method gives a continuous measurement of the light-scattering angle during spray nozzle tests. A method of calibration and a correction for background light are presented. Mean particle diameters of 10 to 500 micrometers can be measured.
