Claim 2
Independent Claim
68 words
A method of application of light to an optical fiber comprising the steps of: bending the optical fiber along a continuous smooth curvature, locating a light dispersing member, made of material similar to or the same as the cover material of the optical fiber, along the bent portion of the optical fiber, and applying light into the bent portion of the optical fiber through the light dispersing member.
Claim 3
Dependent Claim
25 words
The method of application of light to an optical fiber according to claim 1, wherein said optical fiber is bent in a semi-circular round shape.
Claim 4
Dependent Claim
