<P>PROBLEM TO BE SOLVED: To provide a sufficiently small and tough imaging probe. <P>SOLUTION: The optical probe 4 includes: a torque wire 34; an optical fiber 10 positioned within the torque wire 34; a beam director 18 positioned coaxial with and adjacent to one end of the optical fiber 10; and an overcladding 26, positioned adjacent to and over the optical fiber 10 and the beam director 18, the overcladding 26 defining an air gap adjacent the beam director 18 so as to cause total internal reflection of light passing from the optical fiber 10 through the beam director 18. The optical probe 4 includes a beam expander 14 and a beam shaper 16 coaxial with and located between the optical fiber 10 and the beam director 18. <P>COPYRIGHT: (C)2013,JPO&INPIT |
