Multimodal endoscope apparatus

A multimodal endoscope apparatus comprising:

• a multimodal endoscope probe including a fiber optic imaging bundle including a multitude of optical fibers;
• a galvo scanner and fiber collimator that are together capable of directing light to a single optical fiber of said multitude optical fibers;
• an optical coherence tomography system launching a swept laser to the galvo scanner, wherein said optical coherence tomography system includes a swept laser source and an optical tomography detector;
• and
• a fluorescence imaging system including:
• a fluorescence excitation system launching a fluorescence excitation laser to the galvo scanner, and
• a fluorescence emission system receiving a reflected fluorescence emission from the multimodal endoscope probe,
• wherein said swept laser is split at a coupler and directed (1) through a sample arm of said optical coherence tomography system to said galvo scanner, and (2) through a reference arm of said optical coherence tomography system directing light to a mirror for reflection back to said optical coherence tomography detector, and wherein said swept laser has a wavelength of from λ3 to λ4, and said swept laser in said sample arm is directed to a first dichroic beamsplitter on a path to said galvo scanner, wherein said first dichroic beamsplitter blocks wavelengths below λ3 and allows for passage of wavelengths above λ3, wherein λ3 is less than λ4 such that said swept laser passes through said first dichroic beamsplitter.
