The spray quality is a crucial issue for our society. A major concern with pesticide application today is related to off-target movement of spray particles (i.e., spray drift). To date, there have been many in field test procedures performed to measure the spray deposition. One of the most common methods includes using water sensitive paper (WSP) and traditional optical techniques that involve analyzing images. However these systems can be time consuming, expensive, and lack sufficient accuracy. Manufacturers and researchers desire a fast and accurate measurement for characterizing spray deposition. The goal objective of this thesis is to develop new optical tools for the characterization of the deposit. This thesis will focus on the potential of the optical sensor to replace the traditional methods based WSP and thus provide an operational solution.
