  • Patent number: H1740
    Abstract: A video camera system combining a charge coupled device (CCD) with a rotating prism optical element is disclosed. The rotating prism optical element moves an optical image on the transducer surface of the CCD array in precise synchronism with a CCD array clock which is transferring charge between transducer sites of the array. Since charge transfer occurs in synchronism with image movement, the exposure of transducer sites to image blurring or smearing additional optical energy is eliminated. The disclosed apparatus is particularly useful for high-speed, high-resolution, military, possibly airborne, camera systems. The invention also contemplates resolution of color images, with the use of color selective filters over adjacent columns of the CCD imaging array. The invention additionally contemplates utilizing a rotating prism optical element with other types of detectors.
