Abstract: An optical assembly may comprise an input fiber to provide a beam, a process fiber comprising a ring-shaped outer core surrounded by a cladding, and a first beam shifter arranged to receive the beam from the input fiber and to shift the beam spatially to illuminate the ring-shaped outer core of the process fiber. The optical assembly may further comprise a second beam shifter arranged to receive the beam from the first beam shifter and to add skew to the beam that is launched into the ring-shaped outer core of the process fiber.

Abstract: An in-fiber beam scanning system may comprise an input fiber to provide a beam, a feeding fiber comprising an imaging bundle with multiple cores embedded in a first cladding that is surrounded by a second cladding, and an in-fiber beam shifter that comprises a first multibend beam shifter coupled to the input fiber, a graded index fiber following the first multibend beam shifter, and a second multibend beam shifter following the graded index fiber and coupling into the feeding fiber. In some implementations, the first multibend beam shifter is actuated by a first amount and the second multibend beam shifter is actuated by a second amount to shift the beam in two dimensions and deliver the beam into one or more target cores in the imaging bundle.
