Abstract: A spray monitoring device analyzes images obtained from a beam passing through a spray pattern applying a spray to a substrate, and identifies discontinuities in the image as indicative of a discontinuity in a spray pattern. The spray pattern is produced by a plurality of nozzles spaced apart across the substrate for applying a suitable coating thereto. The beam is produced by a laser, that preferably has a collimator for distributing the beam intensity. The beam is imaged by a camera that provides a constant image to a computers where the scattering of beam light by the spray pattern is processed by image processing software and optionally provided to a user interface for analysis. Discontinuities detected by the user or software indicate faulty spray nozzles and may trigger remedial action.
