What is Digital Infrared Thermal Imaging?
From the paper “The Physiological Basis for Clinical Thermography and the Detection of Infrared Radiation from the Human Body.” By Peter Leando (Ref 11) I quote; “The emissivity of human skin is almost 100% (close to black body emissivity) so the human subject is an ideal subject for thermographic imaging. All thermographic images (thermograms) of the human body depend on the sympathetic control of skin blood-flow. Only the dermal blood flow changes explain the heat seen on the surface of the body. The heat of a muscle, a joint or a bone is not conducted to the dermal tissues and...
