Title:
NONREFLECTIVE OPTICAL FIBER
Document Type and Number:
Japanese Patent JPH05181017
Kind Code:
A
Abstract:
PURPOSE:To transmit information without reflection even when the propagation direction of light is changed by composing the optical fiber of a system which is a connection part connecting for plural elements or devices which perform storing, operation, or measurement and forms a linear curve in such a shape that the transmission of light is not impeded. CONSTITUTION:The radius of curvature of the linear curve is cosh(as)/b based upon 1st and 2nd parameters (a) and (b) and coordinates (s) along the curve and a positive integer N and the two parameters (b) and (c) are so determined that b/a=2(N(N+1))<0.5>. A figure (a) when N=1 corresponds to a figure (b) when N=2, the curves actually has no intersection and a spatial interval, and a selfevident knot is obtained, so that the direction of the light can be changed without reflection. Therefore, the nonreflective optical fiber which has the finite radius of curvature is formed as the connection part for plural elements or devices which perform the storing, operation or measurement.
