Paper Abstract

The effects of varying lens housing temperature on subsurface temperature profiling of a tissue-simulating phantom were studied using pulsed photothermal radiometry (PPTR). A temperature feedback system was used to control systematically the infrared (IR) detector lens housing temperature. Temperature feedback system maintained lens housing temperature at constant level for external temperature fluctuation. The radiometric signal intensity and temperature calibration was substantially affected by lens housing temperature change. Temperature values as a function of depth profiles reconstructed from pulsed photothermal radiometry measurements increased when lens housing temperatures were elevated during the radiometric temperature calibration run. These experiments demonstrate that lens housing temperature fluctuations affect the accuracy of radiometric subsurface temperature measurements using an infrared camera system.
