DEVICE FOR BENDING OPTICAL FIBER AND RECEIVING LIGHT

摘要

A device for bending an optical fiber and receiving light is provided with a recessed holding member having a recess, a projecting holding member having a projection projecting toward the recess, light receiving elements for receiving leak light from the optical fiber held between the recess and the projection, and a supplemental support mechanism substantially independent of the recess or the projection and supplementarily supporting the optical fiber between the recess and the projection so that the leak light from the optical fiber is received by the centers of the light receiving elements.
