Abstract: Aspects of the disclosure relate to the use of an optical detection scheme enabling multiple imaging sub-systems concurrently optimized for retrieving multiple characterization modalities. The feature described is an offset illumination and detection arrangement for a multimodal imaging probe. The imaging probe comprises multiple waveguides disposed within a torque-transfer coil, distally terminating at longitudinally separated positions. A first waveguide may have focusing optics for focused illumination and/or detection. Any number of other waveguides may be deployed for illumination and/or detection having no focusing optics. The disclosure enables high-fidelity multimodal imaging systems.
