Abstract: | An image-processing method is proposed to obtain the distribution of the removal efficiency of particles on a plate by an
air jet. This method can be used to measure particle removal from a flat surface by processing the image of the reflected
light from the surface. Factors affecting the particle removal efficiency such as air pressure, distance between the nozzle
and the impinging surface and the impinging angle are discussed. Optimal conditions are determined to obtain the most effective
particle removal by the air jet.
