    Abstract: Systems and methods are provided for presenting three-dimensional content on a display. An exemplary system for presenting a plurality of frames on a display comprises a first lens, a second lens, and an activation system. The activation system utilizes electromagnetic radiation to activate the first lens when a respective frame being presented on the display corresponds to the first lens, resulting in the first lens being substantially transparent and the second lens being substantially opaque, and to activate the second lens when a respective frame being presented on the display corresponds to the second lens, resulting in the second lens being substantially transparent and the first lens being substantially opaque.

  • Patent number: 5481321
    Abstract: A stereoscopic film projection system including one or more electro-optical light modulators used as part of, or in conjunction with, stereoscopic projection optics for the above-and-below film format employed for 35 mm theatrical cinema. The optical state of each modulator is voltage dependent, and the driving voltage therefor is generated in response to signals from a sensor positioned in the projector aperture. The sensor detects the presence or absence of index marks on the film. This arrangement insures that each subframe is maintained in a proper relationship with the optics' polarizers for preventing the projection of pseudostereoscopic motion pictures.

  • Patent number: 5402191
    Abstract: Stereoscopic images are presented by alternately displaying corresponding left eye and right eye images in succession, substantially extinguishing transmission of light from the left eye images to the right eye of a viewer and from the right eye images to the left eye of the viewer, for example by the use of polarizing filters, and alternately and in synchronism with the alternate display of images, scattering unextinguished light from the left eye images that leaks through to the viewer's right eye and from the right eye images that leaks through to the viewer's left eye. In a preferred embodiment, scattering is achieved by using a liquid crystal scattering shutter that is electrically triggered in synchronism with the display of images. The shutter disperses the unextinguished light that leaks through the system so that no image information is perceived and the light appears merely as a slight increase in background illumination.

  • Patent number: 5002387
    Abstract: An alternate eye 3-d projection system has a projector projecting alternate eye left and right images, has alternating eye 3-d glasses alternating between left and right lens transmissiveness, and has a phase delay unit synchronizing the left lens transmissiveness to left images and right lens transmissiveness to right images. A timing shutter is driven through a mechanical link to the projector primary mechanism at a frequency proportional to the frequency of the transition between images. A sensor outputs pulses according to the rotationally frequency of the timing shutter. The phase delay unit receives the pulses, a multiplier multiplies the frequency of the pulses, a phase lock loop locks on to the frequency and a counter counts the pulses. After a preset delay the counter outputs a pulse. The delay is adjustable. The counter pulse enables a 60 KHz oscillator. The oscillations are counted by another counter and passed to a transmitter.

  • Patent number: 4997270
    Abstract: Projected image misalignment in a 3-D motion picture projector is corrected by shifting one of the projection lenses in accordance with a predetermined program during presentation of the motion picture. In one embodiment, manually initiated control signals for adjusting the lens shift are recorded in a memory and can be subsequently retrieved for automatically controlling lens shift. In another embodiment, lens shift is controlled by reading predetermined witness marks on the film.

  • Patent number: 4971435
    Abstract: In an alternate eye 3-D motion picture projection apparatus of the rolling loop type, light projection is accomplished by the combination of focal plane shutters that are coupled to the rotor of the projector and a supplementary shutter arrranged to trim the projected light so that discrete "left eye" and "right eye" images are projected. Various embodiments are disclosed in which a rotary blade shutter is located at the stop of the projection lens. Where there are two projection lenses, a single blade or two counter-rotating blades trim the light projected through both lenses.

  • Patent number: 4623223
    Abstract: Stereo views of a scene are reflected by plano mirrors onto a concave mirror. The plano mirrors are positioned to cause the reflected light from the concave mirror to converge on and cross the optical axis. The concave mirror focuses real images in planar registration in front of the concave mirror and on the optical axis. When viewed from beyond the real images an observer sees a separate stereo view in each eye which combine to provide a 3-D picture.

  • Patent number: 4424529
    Abstract: A stereoscopic viewer system receives a synchronization signal input from a left-right stereoscopic image pair production system. A viewer system has a transmitter and a modulator associated therewith to transmit into a medium a carrier signal modulated with the synchronization signal. A transmitted signal is received by a receiver which has a demodulator to extract the synchronization signal and to supply it to switching logic. The switching logic supplies switching signals to alternately operate selectively and in accordance with the synchronizing signal each of a pair of electro-optic shutters between the maximum and minimum optical transmission state. Each shutter is positioned in the line of sight of one of the eyes of a user. The system receiving means is powered by a battery power supply.

  • Patent number: 4021846
    Abstract: An optical device, useful for three-dimensional stereo viewing not requir any mechanical shuttering, including two liquid crystal lenses, each comprising: (1) a thin layer of liquid crystal material, preferably nematic liquid crystal; (2) two plates of conductively-coated transparent material enclosing the liquid crystal, each plate being connectable to a source of voltage, and each plate being insulated from the other; (3) a front polarizing sheet forming the outside surface of the crystal lens; and (4) a rear polarizing sheet forming the inner surface of the crystal lens. The axes of polarization of the front and rear polarizing sheets are at right angles to each other, with the result that maximum light transmission through each of the lenses occurs when no voltage is applied across the conductively-coated plates, and minimum light transmission occurs when a voltage is applied across the coated plates.
