We report the first miniaturized single-fiber-based imaging+sensing probe capable of simultaneous optical coherence tomography (OCT) imaging and temperature sensing. An OCT lens is fabricated at the distal end of a double clad fiber, including a thin layer of rare-earth doped tellurite glass to enable temperature measurements. The high refractive index of the tellurite glass enables a common-path interferometer configuration for OCT, allowing easy exchange of probes for biomedical applications. The simultaneous imaging+sensing capability is demonstrated on rat brains.en© 2018 Optical Society of AmericaBrainAnimalsRatsDiagnostic ImagingTomography, Optical CoherenceBody TemperatureEquipment DesignFiber Optic TechnologyOptical FibersJournal article003008596910.1364/OL.43.0016820004300845000152-s2.0-85045573412400188Li, J.
