Recognition of Nanoparticle and Microdroplet Parameters in Levitating Microdroplets of Suspension by Speckle Image Analysis Using Convolutional Neural Networks

Yaroslav Shopa, Kwasi Nyandey, Daniel Jakubczyk

Retrieving suspension parameters from light scattered by a suspension microdroplet is a difficult inverse problem because the recorded optical pattern is shaped by droplet morpholo…
