Abstract
A pboto-sensor wherein a bundle of optical fibers is disposed within a predetermined substrate, the optical fiber bundle extending from a first surface to a second surface of the substrate and being formed to be flat, an array of photosensitive elements which have photosensitive parts on an open end face of the optical fibers at the first surface of the substrate is disposed integrally with the substrate, and an end face of the optical fibers at the second surface of the substrate serves as an information reading surface.
Claims22
A photo-sensor comprising a predetermined substrate, a bundle of optical fibers which is disposed in said substrate and which extends from a first surface to a second surface of said substrate, and an array of photosensitive elements which is integrated onto said substrate, said photosensitive elements having photosensitive parts on an end face of said optical fibers at said first surface of said substrate, an
- end face of said optical fibers at said second surface of said substrate serving as an information reading surface.
