Abstract

PURPOSE:To make possible free selective reception of one of multiple informations by receiving the exit light of the 1st optical fiber in the plural 2nd optical fibers provided on the same circumference centering at the optical axis of the 1st optical fiber. CONSTITUTION:Plural photo detecting fibers 2 are diposed equidistantly on the circumference 7 centering on the optical axis of an incident fiber 1. A prism-form mirror 3 which has an angle theta of inclination of its curved face constitutes a refractive optical system with a plane mirror 4. The refractive optical system in the mirrors 3, 4 is rotated within the plane perpendicular to the incident light beam 1-1 by a pulse motor or the like and is so set that its rotating axis 5 aligns to the optical axis of the incident light beam 1-1. Hence, the incident light beam 1-1 and reflected light beam 2-1 are capable of optically and freely performing selection and connection. One of multiple informations may be freely and selectively received.
