20.500.12556/RUL-143806 Reflectance calibration of multimode optical fiber probes by probe-to-target distance reflectance profile modeling Reflectance acquired with a multimode optical fiber probe can be related to optical properties of an investigated turbid medium by utilizing a light propagation model. During this step, a calibration of the light propagation model is required, as the modeled reflectance is normalized to the light energy of the source fiber, while the experimentally acquired reflectance is normalized to a reflective standard. Since currently established calibration methods based on liquid and solid turbid phantoms suffer from drawbacks such as low stability and dependence on other characterization methods, we propose a new method for reflectance calibration that is based on modeling and acquisition of probe-to-target distance reflectance profiles from first surface mirrors. We show that the spectrally resolved calibration factors can be estimated with a repeatability of 2% and agree within 10% with the reference values obtained by using turbid phantoms based on aqueous suspensions of polystyrene microspheres. optical fiber probes reflectance calibration reflectance modeling Monte Carlo simulations optical properties optične sonde kalibracija reflektance modeliranje reflektance simulacija Monte Carlo optične lastnosti true false true Angleški jezik Slovenski jezik Članek v reviji 2023-01-12 13:16:49 2023-01-12 13:16:50 2023-02-22 12:25:33 0000-00-00 00:00:00 2022 0 0 14 str. art. 112002 Vol. 203 15.
