Abstract

We demonstrate a tethered capsule endoscope (TCE), which uses double-clad fiber and reflective optics for multimodal imaging in the esophagus without undesirable chromatic effects, such as focal shifts or back-reflections. We use a single, custom ellipsoidal mirror to focus the light from the fiber tip onto the sample. We describe the mechanical and optical designs and the fabrication and assembly protocols necessary for optimal performance. We demonstrate the implementation of the capsule by performing combined optical coherence tomography and spectral imaging in ex-vivo esophagus.
