20.500.12556/DKUM-66372 Monitoring the evaporation of fluids from fiber-optic micro-cell cavities Fiber-optic sensors provide remote access, are readily embedded within structures, and can operate in harsh environments. Nevertheless, fiber-optic sensing of liquids has been largely restricted to measurements of refractive index and absorption spectroscopy. The temporal dynamics of fluid evaporation have potential applications in monitoring the quality of water, identificationof fuel dilutions, mobile point-of-care diagnostics, climatography and more. In this work, the fiber-optic monitoring of fluids evaporation is proposed and demonstrated. Sub-nano-liter volumes of a liquid are applied to inline fiber-optic micro-cavities. As the liquid evaporates, light is refracted out of the cavity at the receding index boundary between the fluid and the ambient surroundings. A sharp transient attenuation in the transmission of light through the cavity, by as much as 50 dB and on a sub-second time scale, is observed. Numerical models for the transmission dynamics in terms of ray-tracing and wavefront propagation are provided. Experiments show that the temporal transmission profile can distinguish between different liquids. fiber-optic sensors opto-fluidics evaporation monitoring optical micro-cells fiber cavities droplet analysis optični vlakenski senzorji optične mikro celice true true true Angleški jezik Slovenski jezik Znanstveno delo 2017-06-22 11:53:15 2017-06-22 11:54:25 2022-07-11 03:06:33 2019-07-11 15:45:14 2013 0 0 str. 15261-15273 št. 11 Letn. 13 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1424-8220 681.5 10176278 17365526 10.3390/s131115261 1424-8220 URN:SI:UM:DK:BOOG3YAH Sensors_2013_Preter_et_al._Monitoring_the_Evaporation_of_Fluids_from_Fiber-Optic_Micro-Cell_Cavities.pdf Sensors_2013_Preter_et_al._Monitoring_the_Evaporation_of_Fluids_from_Fiber-Optic_Micro-Cell_Cavities.pdf 1 FEE1CB8BFE8079D5647FF15D62446370 0a6c74f3836e1ae8c8764487c85a27db3aaa139611fca893818746ddee8aa28f 487a5eef-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112948 http://www.mdpi.com/1424-8220/13/11/15261/ 1 https://dk.um.si/Dokument.php?lang=slv&id=112947 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
