Abstract

A periscopic display device for close-up viewing of a display. The device includes means for generating a display, such as an LED, LCD, or ELD display, and periscopic means consisting of a body of optically clear material having a reflecting prism portion and a collimating lens portion. The prism portion includes a first planar surface positioned adjacent to the display and at least one optically aligned reflecting surface for transmitting a reflected image of the display. The collimating lens portion consists of a convex lens having a focal point at the display and is positioned to receive the reflected image for focusing the image at optical infinity. Preferably the body includes a mounting portion in which the display generating means is embedded. The display device is lightweight, waterproof, dustproof, and is easily mounted on the eyeglass frames, visor, or headband of the wearer.
