ABSTRACT:
An optical system (10) has an image source (12), a first optical element (34), a second optical element (50), and an aperture stop (52). The first optical element (34) is positioned close to the image source (12) to generate anamophic field curvature of matching the display screen (16). The radiation is then directed to the second optical element (50) which corrects astigmatism of the radiation passing from the first optical element (34). The aperture stop (52) is provided adjacent to the second optical element (50). The system may be used in an infinite display optical system where the radiation would be directed through projector 14 to a screen (16). A mirror (18) is positioned to reflect the radiation from the screen (16) to provide an image to a viewer.
