Crossed Optical Fiber Sensor Arrays for High-Spatial-Resolution Sensing: Application to Dissolved Oxygen Concentration Measurements

Figure 2

Luminophore leaching for different cladding materials: referenced-RuPhen intensity decrease versus time, which occurs because of RuPhen leaching from films made with the following polymers: (a) PEG-DA 575 (b) PEG-MA 1000, and (c) PEG-DA 575 tailored with TPT. The leaching percentages are (a) 71%, (b) 89%, and (c) 50%. The initial values of each curve were normalized to one for better comparison.
