Isolated screenshots of elastic scattering from 2.87-µm particles illuminated with a 375-nm laser and with no filter applied. Note that the images are cropped to focus on the illuminated area. (a) Screenshot showing two particle signals merged into a single particle signal. (b) A brightened and higher contrast version of (a) showing the visible particles missed by the detection algorithm. (c) Example showing unclear particle signals away from the main area of illumination. (d) Example showing a single signal being counted as multiple particles. (e) Example showing the updated detection algorithm tailored to the moving particle signal geometry.
