  • Patent number: 5839808
    Abstract: A projection system is disclosed including a light source for producing an illumination light flux, and a light valve for converting the illumination light flux incident on the light valve into a modulated light flux. The projection system also includes a front lens system having a front optical axis. The front lens system is disposed relative to the light source and the light valve to transmit the illumination light flux to the light valve, and to transmit the modulated light flux toward a rear lens system having a rear optical axis that is displaced from but parallel to the front optical axis. The rear lens system is disposed relative to the front lens system to transmit the modulated light flux from the front lens system onto a suitable surface for viewing.
