High definition video-rate laser-addressed liquid-crystal light-valve projection display

An apparatus for displaying high definition projected images on a distant screen in accordance with a greater than 1000 TV-line resolution at video-image signal rates comprising:

• a laser providing a beam of coherent light;
• means disposed to receive the beam of coherent light for modulating it at the video-image signal rates;
• means disposed to receive the modulated beam of coherent light for tracking the modulated beam of coherent light in a horizontal direction;
• an acousto-optic traveling wave lens disposed to receive the modulated and tracked beam of coherent light for chirping the modulated and tracked beam of coherent light to scan a focused spot along a horizontal line to thereby increase the resolution thereof;
• means disposed to receive the modulated, tracked and chirped beam of coherent light for imparting a scan thereof in the vertical direction;
• means connected to the modulating means, the tracking means, the acousto-optic traveling wave lens and the imparting means for providing signals to control the modulation, horizontal tracking, horizontal chirping and vertical imparting of the beam of coherent light;
• means aligned to receive the modulated, horizontally tracked, horizontally chirped and vertically imparted beam of coherent light for selectively changing the polarization orientation of linearly polarized light incident thereon in direct response to the voltage pattern directly produced therein by the modulated, horizontally tracked, horizontally chirped and vertically imparted beam of coherent light;
• means disposed for projecting a high intensity light beam in a light path to the light polarization orientation changing means;
• and
• a liquid-crystal light valve interposed in said light path between the light polarization orientation changing means and the high intensity light beam projecting means for reflecting linearly polarized high intensity light onto the light polarization orientation changing means and for directing modulated reflected high intensity light modulated in accordance with the modulated, horizontally tracked, horizontally chirped and vertical imparted beam of coherent light onto the distant screen in the form of real-time, high definition images at video-image signal rates at greater than 1000 TV-line resolution.
