Comprehensive study on the use of protective masks done with a LaVision BOS system at the University of Edinburgh

Tuesday, 2. June 2020

With the help of manikin Lucas, scientists in Edinburgh tested the effectiveness of face masks in preventing the spread of viruses.

The experiments lead by the groups of Dr.Ignazio Maria Viola and Dr. Brian Peterson were conducted using the Background Oriented Schlieren (BOS) technique to visualize breathing and coughing both from a real person and from a manikin.

The studies were performed for the subject (human or manikin) equipped with and without face coverings. Altogether seven types of different face coverings were tested.
