MULTIMODAL ENDOSCOPE APPARATUS

摘要

A multimodal endoscope apparatus includes optical components (couplers, collimators, mirrors, beam splitters, filters and the like) structured to work together to interact with a multimodal endoscope probe to provide at least two imaging modalities selected from fluorescence imaging, optical coherence tomography, and photoacoustic imaging. The multimodal endoscope probe includes a fiber optic imaging bundle including a multitude of optical fibers. In embodiments employing photoacoustic imaging, the multimodal endoscope probe further includes a polymer-Fabry-Perot interferometer. In some embodiments, a galvo scanner and fiber collimator are included and are together capable of directing light to a single optical fiber of the multitude optical fibers. The system is modular in some embodiments, allowing for switching of some components.
