A Novel Home-Built Metrology to Analyze Oral Fluid Droplets and Quantify the Efficacy of Masks. (arXiv:2201.03993v1 [cs.CV])

Wearing masks is crucial to preventing the spread of potentially
pathogen-containing droplets, especially amidst the COVID-19 pandemic. However,
not all face coverings are equally effective and most experiments evaluating
mask efficacy are very expensive and complex to operate. In this work, a novel,
home-built, low-cost, and accurate metrology to visualize orally-generated
fluid droplets has been developed. The project includes setup optimization,
data collection, data analysis, and applications. The final materials chosen
were quinine-containing tonic water, 397-402 nm wavelength UV tube …
