Temperature resolution enhancing of commercially available IR camera using computer processing

摘要

As it is well-known, application of the passive THz camera for the security problems is very promising way. It allows seeing concealed object without contact with a person and this camera is non-dangerous for a person. Using such THz camera, one can see a temperature difference on the human skin if this difference is caused by different temperatures inside the body. Because the passive THz camera is very expensive, we try to use the IR camera for observing of such phenomenon. We use a computer code that is available for treatment of the images captured by commercially available IR camera, manufactured by Flir Corp. Using this code we demonstrate clearly changing of human body skin temperature induced by water drinking. Nevertheless, in some cases it is necessary to use addiitional computer processing to show clearly changing of human body temperature. One of these approaches is developed by us. We believe that we increase ten times (or more) the temperature resolution of such camera Carried out experiments can be used for solving the counter-terrorism problem and for medicine problems solving. Shown phenomenon is very important for the detection of forbidden objects and substances concealed inside the human body using non-destructive control without X-ray application. Early we have demonstrated such possibility using THz radiation.
