Optical fibers, dual-coated

Figure 4 Schematic of single and dual coatings for optical fibers.

Figure 15 (a) Optical fiber coating run in dual cantilever bending with notched clamp. Total thickness 150 microns. Cure of the coating can be seen between run I and run 2. (b) Peaks due to ionhopping in glass. 

Petersons pH probe also was modified in order to give a miniature fiber optic sensor potentially suitable for glucose measurements90. Kopelman et al.91 developed a fiber-optic pH nanosensor for physiological measurements using a dual-emission sensitive dye. The performance of a pH sensor was reported92. An unclad fiber was dip-coated with a thin layer of porous cladding within which a pH-sensitive dye was entrapped. The fundamental...
