Testing configuration for simulated human thermographic reading. (a) Regular image. (b). Thermal image. Subject was mounted at 168 cm from the floor. Manufacturer specifications were followed in the placement of the IRTs relative to the subject. All tablets were mounted at a height of 155 cm and placed at a distance of 50 cm from the subject. The FLIR IRT was mounted at a height of 157.5 cm and placed 70 cm from the subject.
Disparity between control (FLIR) and tested IRTs: magnitude and direction of deviation from BB reading. (a) Difference between device and subject versus subject. (b) Absolute value of difference between device and subject versus subject.
