Abstract:
1. A probe for a common path optical coherence tomography system, comprising: a sheath having a proximal end and a distal end, said sheath defining a lumen therein; a single mode optical fiber disposed within said lumen of said sheath such that a portion of said single mode optical fiber extends beyond said distal end of said sheath, said single mode optical fiber having an end face for transmitting and receiving light; and a layer of hardened epoxy encasing said portion of said single mode optical fiber that extends beyond said distal end of said sheath except for said end face, wherein said single mode optical fiber has an optical axis extending along a longitudinal direction of said single mode optical fiber, and wherein said hardened epoxy is polished at a non-orthogonal angle relative to said optical axis at said end face, and wherein said non-orthogonal angle is at least 1° relative to a normal to said optical axis at said end face and less than 5° relative to said normal.
