An image rotating apparatus presents a projected video image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the apparatus, can view the projected video image simultaneously. The video image rotating apparatus utilizes light valve technology to create red, green and blue images from an analog composite video signal, and a Phillips prism that aligns the images produced by the light valves for projection through an optical system. The image produced by the light valves is rotated, either mechanically or electronically, in synchronization with rotation of the projection screen. The projection screen itself eliminates the need for a separate shutter by both expanding the projected image generally parallel to the screen's axis of rotation, and constricting the width of the projected image generally perpendicularly to the screen's axis of rotation.

A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates an image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A rotatable polarized screen and a separate, stationary polarized screen cooperate to define a viewing window which remains continually aligned with the rotating real image in space.

A viewing system is provided for presenting a projected image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the viewing system, can view the projected image simultaneously. The 360.degree. viewing system features an optical system which rotates with respect to a cathode ray tube about the vertical axis in synchronization with the rotation of the projection screen. A liquid crystal display (LCD) screen is utilized to define a viewing window which is continuously redefined at sequential intervals to remain continually aligned with the projection screen.

A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates a black and white image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A liquid crystal display (LCD) screen is utilized to define a filtered viewing window which is continuously redefined at sequential intervals to remain continually aligned with the rotating real image in space. The LCD screen includes normally opaque red, green and blue filter panels which operate to give color to the real image in space.

A cigarette made of cut tobacco rolled in a paper having a refractory layer with a predetermined pattern bonded to or imprinted upon the interior surface of the paper. The pattern is formed outside of rows and columns of what eventually become elongated slots when the paper burns away. The slots are arranged in lengthwise rows and also are arranged in columns. Each row has a slot midpoint which lies midway between slots in each adjacent row.

A flat TV screen is provided by overlapping rows and columns of fiber optics. Each cross-over point will emit more light than radiates from the side of a single optical fiber when both of the crossing fibers are energized. Therefore, a dot matrix can be generated by controlling the entrance of light into the ends of the optical fibers in the rows and columns. The rows of optical fibers are sequentially energized by a light signal of constant brightness. The columns in turn are successively energized during the time period that each row is energized with signals derived from a TV video signal to thereby provide an optical reproduction of the TV signal from the dot matrix of light defined at the cross over points of the rows and columns. A filter covering having the property of emitting light at a given point on its surface only when such point is stimulated by light exceeding a given threshhold in brightness may be positioned over the dot matrix of light so that when the filter covering is used, the dot matrix of light is reproduced with higher contrast than in the absence of the covering.

The entrance ends of a plurality of optical fibers are arranged in a circular array and each provided with light emitting material in the form of phosphor responsive to impingement of an electron beam. The circular array of the fiber optic entrance ends is scanned by an electron beam so that the light emitters are successively triggered, the time for light to travel the difference between successive light paths defined by the optical fibers corresponding to the time of scan from one light emitting phosphor to the next adjacent light emitting phosphor so that individual pulses of light exit from the ends of said fibers substantially simultaneously.

Light fibers having lengths determined by beam scanning time

The assembly includes a plurality of individual pulse lasers arranged to be successively triggered at predetermined time intervals. A single light transmissive body receives the output pulses from the lasers at different input angles so that the respective pulses follow different path lengths in the body. The sequence of firing of the lasers and the respective angles are such that pulses exiting from the body will all exit substantially simultaneously. The result is a high energy concentration of output light.

Multiple pulse laser assemblies

A laser beam is scanned in a circular pattern so that it will successively impinge upon light entrance ends of a plurality of optical fibers arranged in a similar circular array. Successive fibers differ in path lengths in such a manner that the light from the scanning laser beam exits substantially simultaneously from the exit ends of the fibers so that a relatively high intensity or amplitude light pulse results.

Annular scanning light pulse system

A steady light beam such as continuous wave, constant amplitude coherent light as provided by a laser, is moved through a given acute angle at a given frequency. The light beam is passed into a solid body of light transmissive material while moving through the given acute angle such that the initially received light in the body when the beam starts its movement through the acute angle follows a first path of a first given length before it emerges from the body. Subsequently received light in the body when the beam has completed its movement through the acute angle, in turn, follows a second path of a second given length different from the first given length before it emerges from the body. The referred-to-frequency is adjusted to define a time increment for the beam to move through the referred to given acute angle. This time increment is made substantially equal to the time it takes light to travel a path length in the body equal to the difference in the referred to first and second given lengths. With such an arrangement, the light beams entering the body at the extremes of the acute angle will exit or emerge from the body coincidentally in time thereby resulting in a high amplitude pulse. These high amplitude pulses are generated at the frequency of movement of the beam through the referred to acute angle.

Method and apparatus for converting steady light into output light

The system involves splitting the light spectrum from a color picture to be reduced in size into first and second spectral portions which are simultaneously photographed with black and white film. The black and white film can be reduced to an extremely small size for storage. Reproduction of the color picture is accomplished by projecting simultaneously from both black and white film images the respective light spectral portions and recombining them to produce the full color picture.

Color coding and decoding system for use in micrographics

A picture in the form of a print or projected image onto a rear view screen in a suitable mounting is positioned in a vertical plane and the mounting then rotated extremely rapidly about a vertical axis exactly bisecting the picture in the plane. With this arrangement, each person in an audience surrounding the mounting over 360.degree. can view the picture each time the viewer's line of sight is normal to the plane of the picture so that, in effect, the entire audience regardless of their position over 360.degree. can view the single picture simultaneously.
