Abstract
Abstract A laser beam guiding fiber comprising, in a tip portion of an optical fiber, an oscillating member which oscillates the tip of the optical fiber along a direction which intersects an axis of the optical fiber can irradiate a wide range with laser beam, since the tip of the optical fiber oscillates by means of the oscillating member along the direction which intersects the axis of the optical fiber and the irradiated position with the laser beam reciprocates periodically with the oscillation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A laser beam guiding fiber having an enlarged irradiating range comprising: an optical fiber having a tip portion; and means, in contact with said optical fiber, for oscillating said tip along a direction which intersects an axis of said optical fiber, said tip portion extending along a longitudinal direction thereof beyond said oscillating means, a said optical fiber being freely movable in said longitudinal direction to thereby change a length of said tip portion extending beyond said oscillating means.
Claim 2
Dependent Claim
79 words
A laser beam guiding fiber having an enlarged irradiating range comprising: an optical fiber having a tip portion; and means, in contact with said optical fiber, for oscillating said tip along a direction which intersects an axis of said optical fiber, said tip portion extending along a longitudinal direction thereof beyond said oscillating means, a said optical fiber being freely movable in said longitudinal direction to thereby change a length of said tip portion extending beyond said oscillating means.
Claim 3
Dependent Claim
50 words
The laser beam guiding fiber according to claim 1, wherein said oscillating means comprises a supersonic oscillator radiating a supersonic wave along the axis of said optical fiber and a supersonic detector for detecting a supersonic wave reflected from an object which exists along the axis of said optical fiber.
Claim 4
Dependent Claim
21 words
The laser beam guiding fiber according to claim 1, wherein said oscillating means comprises two oscillating members sandwiching said optical fiber.
