The internal surface of both the top portion and the bottom portion of the chamber is coated with a reflective material in order to produce an optical and acoustical illusion of a 3-dimensional image and sound of a human life-size object positioned inside the chamber. Another embodiment of the invention comprises an integral reflection-type hologram having both horizontal and vertical parallaxes, and projecting an orthoscopic real image perpendicularly from the floor in order to produce an optical illusion of a human life-size 3-dimensional image.
Brief Description of the Figures in the Drawings ~ In drawings which illustrate embodiments of the invention:
o Figure 1 marked "Prior Art" is a sectional view of a conventional optical illusion device;
o Figure 2 is a sectional view of one embodiment of a life-size optical and acoustical illusion device according to the invention;
o Figure 3 is a sectional view of another embodiment of a life-size optical and acoustical illusion device according to the invention; and o Figure 4 is a perspective view of another embodiment of a life-size optical illusion device with a hologram according to the invention.
Modes for Carrying Out the Invention ~ In one conventional optical illusion device shown in Figure 1 marked "Prior Art", a small object 1-3 is placed inside a small chamber having a paraboloidal top portion 1-1 which is partially open at the top centre, and a paraboloidal bottom portion 1-2.
~ The internal surface of both the top portion 1-1 and the bottom portion 1-2 of the chamber is coated with a reflective material in order to produce an optical illusion of the object 1-3. An observer 1-5 looks downward toward the reflective surface of the chamber in order to view a 3-dimensional image 1-4 of the object.
~ In this conventional optical illusion device, also known as the "Optic Mirage (Trade Mark)", the object may be live or inanimate, but the size of the object is limited. Moreover, there is only one storey of chamber to raise the image of the object. According to the present invention, the chamber is large enough to accommodate a human life-size object, which may be live or inanimate. The path of light rays is indicated by arrows in each Figure.
~ In one embodiment of the invention shown in Figure Z, a human life-size object 2-3 is placed inside a large chamber having a paraboloidal top portion 2-1 which is partially open at the top centre, and a paraboloidal bottom portion 2-2 which is partially open at the side in order to receive a human lif.e-size object. The paraboloidal top portion 2-1 and the paraboloidal bottom portion 2-2 are securely attached together. A ring-shaped platform 2-6 around the opening of:
the top portion of the chamber is securely attached to the external surface of the top portion 2-1 of the chamber in order to receive an observer 2-5. A long staircase 2-7 leads from the floor to the platform 2-6, and is securely attached to the platform 2-6. A short staircase 2-8 leads from the floor to the bottom portion 2-2 of the chamber, and is securely attached to the bottom portion 2-2 of the chamber.
~ The internal surface of both the top portion 2-1 and the bottom portion 2-2 of the chamber is coated with a reflective material in order to produce an optical and acoustical illusion of the object 2-3. An observer 2-5 looks and listens downward toward the reflective surface of the chamber in order to view a life-size upright 3-dimensional image 2-4 of the object, and to hear the sound from the object.
~ In another embodiment of the invention shown in Figure 3, a human life-size object 3-3 is placed inside the bottom chamber 3-0-I, which is securely attached to at least one additional chambers, 3-0-2, 3-0-3, and 3-0-4 in this example.
Each additional chamber has a paraboloidal top portion which is partially open at the top centre, and a paraboloidal bottom portion which is partially open at the bottom centre.
A ring-shaped platform 3-6 around the opening of the top portion of the top chamber 3-0-4 is securely attached to the external surface of the top portion of the top chamber 3-0-4 in order to receive an observer 3-5. A long staircase 3-7 leads from the floor to the platform 3-6, and is securely attached to the platform 3-6. A short staircase 3-8 leads from the floor to the bottom portion of the bottom chamber 3-0-1.
~ The internal surface of both the top portion and the bottom portion of each chamber is coated with a reflective material in order to produce an optical and acoustical illusion of the object 3-3. An observer 3-5 looks and listens downward toward the reflective surface of the top chamber in order to view a life-size upright 3-dimensional image 3-4 of the object, and to hear the sound from the object, ~ In another embodiment of the invention shown in Figure 4, a plurality of reflection-type holograms are securely attached together in order to form a single integral reflection-type hologram 4-l, which is horizontally placed on the floor. ;~
point source of coherent or white light 4-2 is placed directly above the reflection-type hologram 4-1 in order to illuminate the reflection-type hologram 4-1. Means for mounting the point source of coherent or white light 4-3 is securely attached to the floor.
~ The integral reflection-type hologram 4-1 projects an orthoscopic real image 4-4, which has both horizontal and vertical parallaxes, perpendicularly from the floor in order to produce an optical illusion of a human life-size upright 3-dimensional image, which is viewed by an observer 4-5 looking downward toward the integral reflection-type hologram 4-1 on the floor.
~ The integral reflection-type hologram 4-1 may be substantially circular, or substantially square or rectangular. Preferably, the integral reflection-type hologram 4-1 is computer-generated, and has full colour.
Technical Field ~ This invention relates to optical and acoustical illusion devices, more particularly to a human life-size optical and acoustical illusion device.
Background Art ~ There are many instances where it would be desirable to be able to have optical and acoustical illusion devices for displaying 3-dimensional images and sounds.
