Abstract
Abstract A vehicle viewing system for use on vehicles to enhance the vehicles' safe operation by minimizing blind spots. The system has an objective assembly mountable on the vehicle with its field of view substantially encompassing a blind spot. The images within the field of view are carried from the objective assembly to a viewer assembly via an image relay system. The image relay system may be a conventional fiber optic cable or a periscope assembly mounted between two fiber optic cables to extend the image transmission. The periscope assembly utilizes a lens assembly to relay images. The viewer assembly is mountable in an easy-to-see location on the vehicle suitable for viewing by the vehicle operator. The objective assembly has a lens system to enable the system to present continuous color images for viewing.
