Bezkontaktní měření tělesné teploty - laboratorní úloha

Abstract

Temperature is one of the most fundamental physical, non-electrical quantities, which we and all the phenomena of nature influences. The temperature should be monitored (measured) and then diagnosed. Body temperature tells much about the physicalcondition of the patient, diagnosis increased (37 ˚C and above), or high temperature (39 ˚C and above) may indicate a malfunction of an organ, or may indicie inflammation or any of the immunological processes in the human body. You could say that the temperature is accompanying a warning signal for the subsequent diagnosis of the patient. Temperature measurement can be only approximate (using mercury thermometers with an accuracy of 1˚C) to improve the accuracy of temperature measurement is taken non-contact thermometers with an accuracy of ± 0.1 ˚ C. An important part of the measurement is also the transfer of non-electric variables (temperature) on the electrical variable (voltage / current) in the measuring chain provides the A / D converter.
