Claim 13:
14. A system for capsule-based multimode endoscopy, comprising:
a visible light imaging system comprising:
a visible light source; and
a visible light detector;

an optical coherence tomography (OCT) imaging system comprising:
an OCT light source;
an OCT detector;
a sample arm optically coupled to the OCT light source and the OCT detector; and
a reference arm optically coupled to the OCT light source and the OCT detector, the reference arm comprising a reference reflector; and

a probe comprising:
a rigid capsule;
a flexible tether coupled to a proximal end of the capsule;
a rotatable reflective surface disposed within the capsule;
a first lens disposed within the capsule;
a first optical fiber optically coupled to the first lens and the sample arm of the OCT imaging system,
the first optical fiber passing through the flexible tether;

a second optical fiber optically coupled to the first lens and the visible light imaging system, the second optical fiber passing through the flexible tether; and
a second lens disposed between a distal end of the second optical fiber and the first lens and not disposed between the first optical fiber and the first lens,
the second lens optically coupled to the second optical fiber and the first lens.
