Abstract

We demonstrate an all-reflective tethered capsule endoscope (RTCE) utilizing double-clad fiber and reflective optics for achromatic multimodal imaging of the esophagus. This device uses a custom ellipsoidal mirror to focus the light from the fiber tip onto the sample. In this work, we first describe key design parameters and highlight important assembly steps. We then demonstrate several data processing/analysis methods for signal multiplexing, rotation stabilization, and image analysis. Finally, we demonstrate the implementation of the capsule by performing combined OCT and spectral imaging in ex-vivo biological samples.
