“…The total emitted intensity I depends on temperature T as I =€aT4 , where a is the Boltzman constant and is the emissivity. There has been some preliminary work which described the use of infrared fibers [1][2][3][4], particularly silver halide fibers, in such thermometry. Silver halide fibers were chosen because they are highly transparent in the infrared wavelength range of 2 to 2Om, flexible, non-toxic and insoluble in water.…”

Infrared fiber (ER) optic radiometry of thermal surfaces offers several advantages over refractive optics radiometry. It does not need a direct line of sight to the measured thermal surface and combines high capability of monitoring small areas with high efficiency. These advantages of JR fibers are important in the control of non-uniform temperature distributions, in which the temperature of closely situated points differs considerably and a high spatial resolution is necessary. The theoretical and experimental aspects of such radiometry are discussed in this report.Theoretical and experimental transforming functions of the sensor during scanning of an area with a non-uniform temperature distribution were obtained and their dependence on the spacial location of the fiber and type of temperature distribution were analyzed. Parameters such as accuracy and precision were determined. The results suggest that JR fiber radiometric thermometry may be useful in medical applications such as laser surgery,hyperthermia and hypothermia.

Silver halide fiber optic radiometric temperature measurement and control of CO₂ laser‐irradiated tissues and application to tissue welding

Tissue heating by laser irradiation has attained importance in many clinical applications. Accurate temperature measurements of laser-irradiated tissues are difficult to achieve, and experiments have produced conflicting results. Fiber optic radiometry allows temperature measurement of laser-irradiated tissues by remote sensing of the emitted infra red (IR) radiation. We have developed an IR fiber optic radiometer capable of accurate tissue temperature measurements (+/- 0.2 degrees C) and utilized it to monitor and control the heating of tissues by CO2 laser irradiation. Tissue temperature control of +/- 2.5 degrees C was achieved. This system was used to control tissue temperature during CO2 laser-assisted welding of urinary bladders in rats. The strength of the welds was recorded for different welding temperatures. A temperature of 55 degrees C was found to be optimal.
