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 properties of an investigated turbid medium by utilizing light propagation model. During this step, calibration the model is required, as modeled reflectance normalized energy source fiber, while experimentally reflective standard. Since currently established methods based on liquid and solid phantoms suffer from drawbacks such low stability dependence other characterization methods, we propose new method for that modeling acquisition probe-to-target distance profiles first surface mirrors. We show spectrally resolved factors estimated repeatability 2% agree within 10% reference values obtained using aqueous suspensions polystyrene microspheres.
