Infrared has already been in use by medical professionals to screen patients for fever, but person-to-person testing requires a close proximity and the wearing of personal protective equipment. As we saw from the beginning of the Covid-19 pandemic, the supply of PPE can be expensive, and easily run dangerously low. Finding a safe and cost-effective solution that does not fall victim to scarcity is the only logical alternative.
Physical screening barriers in offices, medical facilities, airports, sports venues, and any other location where humans interact is the first step to preserving a healthy environment. The problem with using physical barriers such as plastic or plexiglass is that infrared cannot see through these materials. While the barrier is necessary, there also needs to be a way to scan people safely and accurately.
