ことを特徴とするフアイバ投光／受光器。 an optical fiber, a lens system that converts the output light from the optical fiber into parallel light for exiting as spatially propagating light, or converts the spatially propagated light into focused light for entering the optical fiber; and optical fiber propagation. It is composed of a light traveling direction converting element that changes the traveling directions of light and spatially propagating light, and a Fresnel lens is used as the lens system.
A fiber projector/receiver characterized in that a lens is provided directly on the light traveling direction converting element.
