A fiber optic interferometer based on core diameter mismatch is used in reflection mode to study the behavior of ethanol solutions with regards to concentration dependent thermal properties and phase transitions. A method to simultaneously measure both temperature and ethanol concentration in systems with non-linear sensitivities has been developed and characterized. © OSA 2018 © 2018 The Author(s)
