Abstract
Abstract An optical system for presenting an observer at a viewing position with a view of the outside scene and with a view of an image of an interior scene in which an image combiner mounted between the viewing position and the outside scene forms a negative lens and a positive mirror with relation to a cathoderay tube phosphor, for example, located below the combiner axis to provide an observer with an aplanatic image of the phosphor. An astigmatic element is disposed between the phosphor and the combiner for correcting the phosphor image for astigmatism. The combiner body comprises a portion spaced outwardly from the partially reflecting surface-forming mirror to compensate for the lens effect of the rest of the combiner on the image of the outside scene.
