Abstract
In this study, we experimentally determined the influence of fibers’ geometrical parameters on the performance of fiber-optic temperature control system based on silver halide fibers at the temperatures of 295–395 K. It was revealed that the fiber diameter can affect thermal radiation transmission in the case of mismatching light beam diameters between system’s optical elements and it should be taken into consideration when such systems are developed. A fiber length reduction leads to a linear increase in transmission values. We also assessed transmission losses for the fibers bent at various radii and derived some empirical equations for calibration curves. The revealed dependencies can be very useful for designing fiber-optic systems intended for remote temperature measurements and control of heating-power facilities’ thermal regimes.
