💨 Abstract

A British-made laser screen is being used at a secure mental health facility and US prisons to detect and pinpoint attempts of contraband deliveries or escapes, including drone landings. The laser system, called 'laser shield', creates a virtual curtain and can be used horizontally or vertically to secure windows or courtyards. It's accurate to within 10cm and can be used to create an invisible virtual ceiling.
