Jr.Assistant: Dowling, William C. Attorney, Agent or FirmInternational ClassG03B 021/26AbstractThe optical system projects discrete images in adjoining relation on a view screen to form a single image with substantial no illuminance discontinuity at the juncture of the images. A pair of afocal lenses split the light rays from a source for passage through segments of the lenses and each discrete image display. The light rays from the image displays are returned to an optical axis through a projection lens such that the adjoining margins of the images on the view screen pass along the optical axis of the projection lens. | |
