Abstract
The disclosed embodiments relate to multimodal imaging system, comprising: a fiber-coupled fluorescence imaging system, which operates based on ultra-violet (UV) excitation light; and a fiber-coupled optical coherence tomography (OCT) imaging system. The multimodal imaging system also includes a fiber optic interface comprising a single optical fiber, which facilitates light delivery to a sample-of-interest and collection of returned optical signals for both the fluorescence imaging system and the OCT imaging system. During operation of the system, the single optical fiber carries both UV light and coherent infrared light through two concentric light-guiding regions, thereby facilitating generation of precisely co-registered optical data from the fluorescence imaging system and the OCT imaging system.
