ABSTRACT:
An apparatus for photo-electrically interfacing a mechanical camera component to an electrical camera component in a camera. The mechanical camera component has a sensing area associated therewith. The sensing area contains optically detectable information. The apparatus comprises a device for directing radiant energy to and from the sensing area. The radiant energy is incident upon at least a portion of the optically detectable information contained on the sensing area. A detecting device is optically coupled to the directing device for photodetecting radiant energy received from the optically detectable information. The detecting device provides an electrical output for receipt by an electrical camera component. The operational status of the mechanical camera component is determinable by the output of the detecting device. The directing device includes an optical fiber having a distal end and a proximal end. The distal end is remotely situated adjacent to the sensing area to permit emission of radiant energy thereon and reception of radiant energy reflected therefrom. The proximal end is locally situated adjacent to an electrical camera component and is optically coupled to the detecting device to permit photodetection of radiant energy reflected from the sensing area.
