The characterization of spray behavior especially the droplets diameter distribution plays an important role in many applications. In this paper, the droplets diameter distributions of a flat fan water spray were measured using both the Global Rainbow Refractometry (GRR) method and sampling method with microscope analysis. a rainbow parameter inversion algorithm is proposed and applied to the GRR measurement, which based on regularized NNLS and regularization method. The sampling droplets were detected using a microscope, and the droplets images were transformed and rebuilt by several image processing techniques. The experiment results from both methods were compared and the errors were analyzed.
