Working Principle of the Particle Size Analyzer Powered by Machine Learning

Caption

(a) A schematic of the experimental setup for measuring particle suspensions showing the optical hardware consisting of a fiber coupled LED, a CMOS image sensor camera and the polymer angular spatial filter (ASF). (b) Working principle of the ASF: scattered light from particle sample is collected up to specific cumulative cut-off angles defined by the geometrical dimension of the holes. Only two holes are represented for simplicity but in the initial experiments 23 holes with different diameter (i.e. cut-off angles) were used. (c) Lab prototype of optical hardware at ICFO. The complete device shipped to Leeds and Dresden for measurements was built in a proper case together with the control electronics.
