In The Abstract of the Disclosure An image display system comprising a cathode ray type of tube having an electron gun disposed for directing an electron beam onto an output phosphor screen provided with quadrant portions extending from a common point and made of respective different phosphor materials; a beam directing assembly coupled to the electron beam for deflecting the beam over each of the quadrant portions sequentially in a manner in- verted in at least one aspect relative to the deflection of the beam over the other quadrant portions and producing thereon a respective component image of a subject inverted in at least one aspect relative to the other component images; and an optical combiner assembly coupled to the output screen for combining the component images and producing a single composite image of the subject. The optical combiner assembly includes a beamsplitter disposed in alignment with one of the quadrant portion and oriented at an angle with respect thereto for directing first and second portions of an image received from the aligned quadrant portion along respective first and second paths to respective first and second reflectors, combining the resulting reflected portions received back from the first and second reflectors, and directing the combined portions along a third path to the output of the optical combiner assembly.
