Estimating the term…
A photo-sensor wherein a bundle of optical fibers in the form of a sheet is disposed within a predetermined substrate, the optical fiber bundle extending from a first surface to a second surface of the substrate, an array of photosensitive elements is disposed integrally with the substrate in such a manner that at least one transparent insulating layer intervenes between the photoelectric elements and the optical fiber bundle on, at least, an end face of the optical fiber bundle on the first surface side of the substrate, and an end face of the optical fiber bundle open to the second surface of the substrate serves as an information reading face.
A photo-sensor wherein a bundle of optical fibers extending from a first surface to a second surface of a predetermined substrate is disposed within said substrate, an array of photosensitive elements is integrated onto said substrate in such a manner that at least one transparent insulating layer intervenes between the photoelectric elements and an end face of the optical fiber bundle on the first surface side of said substrate, and an end face of said optical fiber bundle located on said second surface of said substrate serves as an information reading face.
