Abstract
A fiber optic video viewfinder for a motion picture camera. The conventional ground glass focusing screen of the camera is replaced by a fiber optic element that comprises a fused coherent bundle of optical filaments. A front face of the fiber optic element is located at the focal plane of the camera. A video imaging device such as a photodetector array is secured to the opposite face of the fiber optic element.
An image presented at the front face of the fiber optic element is transmitted through the element to the video imaging device whose electrical outputs are converted into a video image. The fiber optic element may be tapered to provide image magnification or demagnification.
