  • Scanning lens system
    Patent number: 4081207
    Abstract: A circular scanning lens system comprises a Petzval lens device having an optical axis on which are located first and second spaced lenses. A Rantsch derotator is positioned between the lenses and has an optical axis coincident with the axis of the Petzval lens, about which elements of the derotator are turned. The scanning lens system is adapted to be used with a raster scan system to remove the tendency of the raster scan system to rotate an image as the image is deflected in a straight line across a focal plane.
