We report an all-fiber system aided by double-clad fiber (DCF) and DCF devices for simultaneous measurements of optical coherence tomography (OCT) and fluorescence spectroscopy (FS). The DCF together with DCF coupler and single-body DCF lens helped in realizing a multifunctional single-unit probe for the OCT-FS system. The fiber lens formed on the DCF aids in effective focusing and signal collection, while the DCF coupler collects the OCT signal from the core and the fluorescence signal from the cladding of the DCF. The OCT image and fluorescence spectra of plant tissues are simultaneously measured and presented to validate the performance.
