       BACKGROUND OF INVENTION  
       [0003] 1. Field of Invention  
       [0004] This invention relates to the image display devices, specifically to 3DTV, hologram, stereo display device that are used for displaying the 3 dimensional object or images and 3D scanners. 2. Description of Prior Art  
       [0005] In the conventional way, it was difficult to display the 3 dimensional object or images in real time (run time) by viewed by the multiple users without special glasses in the space only by light. So devices such as TV are showing the converted 2 dimensional image from the 3 dimensional objects. Also, the virtual headsets are showing the two different images to each eye of users by screens to create the 3 dimensional images. Also, holograms are showing 3 dimensional image, but these images are difficult to be changed in real time (run time). Also, the method to project the 2 dimensional image to rotating plate to create 3 dimensional image are difficult to show the 3 dimensional virtual images in the space only by light. Also, the method to project the 2 dimensional image to semi-transparent plates to create 3 dimensional image are difficult to show the 3 dimensional virtual images in the space only by light. In other words, user cannot touch these 3 dimensional images to interact directly with the 3D image. These are like U.S. Pat. No. 5,394,202 (Deering, 1995) and U.S. Pat. No. 5,907,312 (Sato, et al, 1999).  
       [0006] In Japanese Patent No 288957, Felix Gashia, et al. shows the way to make 3 dimensional image by project the 2 dimensional image to rotating plate. This put red, blue, green laser beam together to light fiber, and run the light to make the 2 dimensional image on the angled and rotated plate so that it would show the 3 dimensional image as a result. But, this one is rotating fast; this is not too safe to users. And therefore, it is not suitable for user to touch the 3 dimensional image. Also, this by itself is almost impossible to show the image in the space only by light.  
       [0007] In the Lab note made by Kazutora Yoshino (May 30, 1995), or in U.S. Patent application No. 60/004,111(1995), or in U.S. Pat. No. 6,302,542 (1999) Tsao shows that the movement of panel/screen with 2D image projected on it can make 3D images. They show little information how fast the panel/screen should movement is made practically nor they show little mechanism how to move the panels/screens effectively in order to make the 3D image realistic. Also, users cannot touch to the 3D image in this method. Also, even when a viewer likes to see background sight through the object, a screen stops the background sight and the viewer could not see the back ground sight. Also, there was a problem such that the movement of back and force in slider-crankshaft-wheel system is harmonic so that the panel movement in space in time was not equally spaced, therefore, the 3D image doesn&#39;t become proportional if image is displayed in a constant timing. Also, in most cases of current technology, 2D image from previously made 2D pictures are projected screen that moves to make 3D image. But in this method, it can display only previously made 3D images only or it is not fast enough for users to interact. This is a problem when users try to interact with 3D images. Also, there was a problem such that when the 2D image was projected a screen, 3D image is too light for viewer to see especially in bright environment since the projection of optic 2D picture image on screen gives light image. In U.S. Pat. No. 5,956,172 (1999) and No. 5,684,621 (1997) by Elizabeth Anne Downing, it shows the way to display the 3D image in a crystal. But user still cannot touch to the 3D image. Also, coupling (intersecting) two light beams is difficult and expensive in many cases since it need to use more direction specifying device such as galvanometers. Also, it is difficult and expensive to create big crystal used in these methods. Also, these methods do not show how to make full color 3D image. It may show only red, green and green color.  
       [0008] In U.S. Pat. No. 3,647,284, (1970) Virgil B Ethlgs, et al. show the method of showing 3 dimensional image made by the light that was originally scattered by an object. This device put two dish means facing each other. The top dish means has a hole in the middle and 3 dimensional image shows up over this hole when user put the object at the bottom of the bottom dish means. But this device by itself would be unsuitable to show the real time (run time) 3 dimensional image.  
       [0009] In U.S. Pat. No. 5,899,861 (1999) Friemel et al. shows the way to acquire the baby image in a body. The system uses the echo of ultrasound to acquire the image of the baby.  
       [0010] In U.S. Pat. No. 5,818,959, Webb, Jon A. shows the making 3D image from 2D images identifying the same points in the picture. But there is not clear description of how to find the identical point in 2 dimensional images that is difficult to practice.  
       [0011] There is a method to use triangular red laser beam or meshed pattern on an object to scan the 3D image in the field of reverse engineering.  
       [0012] Neither of these is integrated enough to acquire and show the 3D images purely in the air with the change of images in real time. That is, displaying the 3D image that user can touch instantly after acquiring the 3D image.  
       OBJECTS AND ADVANTAGES

       SUMMARY  
       [0024] This device of invention can display the 3 dimensional objects or images in real time (run time) by the multiple users without special glasses in the space.  
       [0025] General concept of the device is to acquire the 3D image from its input device means using optical camera, optical video, laser scanner, ultrasound. Or one can make 3D image using design program such as CAD program by computers. Then a 3D image generator displays the acquired 3D images or generated 3D images. In order to display the 3D image, it runs the light emitting point means in the 3 dimensional spaces so fast that the resultant light image creates 3 dimensional image.  
       [0026] When a beam or beams with enough energy enters material means such as plasma such as air plasma like oxygen plasma &amp; nitrogen plasma or gas like argon, helium, and air or liquid like liquid crystal, and solid such as a crystal, glass, plastic, the material means emits the light from the point. Usually, projecting invisible beams such as infrared light to let the material means such as crystal, gas, and plasma to emit visible light such as red light is what is practical. For example, microwave beam creates a plasma and plasma glow emitting photons with gases. By concentrating beams such that each has energy less than the thresholds yet when they are gathered into a same spot, it would have the energy that goes beyond the thresholds to emit the photon(s).  
       [0027] In this method, the device can generate 3D created image in the middle of air using air plasma (oxygen and nitrogen plasma) as the result of beams projections. Also, the device can generate 3D created image in a gas within a container as the result of light emission from the gas at the focused point where beams are projected.  
       [0028] If gas, liquid, solid such as crystal is volumetric, the concentration of such beam is necessary. But, if the gas, liquid, solid such as crystal has thin layer, the beam entrance to the thin layer creates a point where it is bright, that is, it creates the virtual point.  
       [0029] By running virtual point very fast (preferably 70 images/sec or greater) or distributing the virtual points, a device can create 3 dimensional image(s). If the thin layer of gas, liquid, solid such as crystal is used, those need to be moved to create 3 dimensional image(s).  
       [0030] When 3D core image is made by 3D core image generator, if the 3D core image is not touchable, the system can have 3D core image lifting means such as inside reflective curved surface means, lens, and reflectors. For example, if the 3D core image is mad in a crystal, it can be embedded to inside reflective dishes-like container or an inside reflective sphere/bowl-like container. The sphere/bowl-like container can be half clear material so that viewer may be able to see the background sight through the image. Also, using simple lens in front of 3D core image can bring the image in front of viewers.  
       [0031] As for the case of the invention that the diffuser/reflector means move with image projection generates the 3D created image, it gives better 3D image when position/motion feed back system is introduced using sensing devices such as encoders, potentiometer, switch ultrasound position reader, motion sensor, gyroscopes direction sensor.  
       [0032] In order to make the position control practical, controlling system means such as pulse width method (PWM) control for DC motor and position sensing device such as encoders (and stepping motor driver and stepping motor, etc.) can be used so that it would not simple reciprocating motion but can choose the designated z coordinate position at right time.  
       [0033] Also a couple of oval gears can be used to modify the speed of rotation so that the special movement in time becomes more uniform comparing to the harmonic movement which is generated by a slider-crankshaft-wheel system.  
       [0034] In order to solve the problem such that 2D image projection on moving screen can display only previously made 3D image or it is too slow to interact or it, the invention can register the data of 0 dimensional image, ID image, 2D image, and 3D image and it sends the information to the image driver means with timing device so that it can have enough images on the moving panel and therefore it generates 3D created image for user to interact.  
       [0035] This invention is innovative on the fact that it uses movement of a layer or layers of the material means such as crystal, plasma gas, gas, special paper/plastic that emit bright light when beam enters to those materials so that when image is made though this system, it gives bright 3D created image as the result of image emitting and movement of a layer or layers of the material means. This solves the problem such that 3D image is too light to see in the bright environment. (Also putting higher power of beam can solve the problem, but this is usually more expensive to do.)  
       [0036] Also, this invention solves the problem such that the controlling devices for coupling beams are expensive since when a beam enters to a point on a layer or layers of those material means, only the point emits the light rays so that the beam does not have to be coupled in this method, which reduce the cost to make.  
       [0037] Also, this invention solves the problem such that viewer could not see the background sight when a screen was used since the screen blocks the background sigh as well in order to capture 2D image. This is because the material means such as plasma, gas or crystal can be clear or clear enough so that viewer can see the background sight through them, meanwhile those material can still emit the light rays for image on the necessary positions.  
       [0038] As for the case of the invention using crystal, in order to solve the limited color graphics, the invention uses timed beam each of which correspond to emission of each color such as red, green and blue. This may be done by pulse width method (PWM) that sends the signals that has different width of pulses having certain intervals of frequency between pulses. This therefore leads emit beam and emit the photons of red, green and blue color wavelength. The fast sequential timing of these color light creates the full color of 3D image for viewer&#39;s eyes.  
       [0039] Also in order to make this 3D image touchable to user, the system may use the 3D core image lifting means such as dishes-like surface with a hole and lens means.

     DETAILED DESCRIPTION  
     [0112] Description—FIGS.  1 , 2 , 3 , FIG. 1_A 3 —Preferred Embodiment  
     [0113] A preferred embodiment of the “3 dimensional image projector and holodeck” is illustrated in FIG. 1, FIG. 2, FIG. 3, FIG. 1_A 3 .  
     [0114]FIG. 1 shows the example diagram of 3 dimensional image projector means { 1 } displaying a 3D created image in the air. The 3 dimensional Image Generator of the type of FIG. 1_A 3  (e 1 ) has z axis control means { 32 } such as focusing beam means { 8 } such as microwave lens, and lens, magnet, and electric magnet together with beam direction changing means { 52 } such as x control means { 30 } and y control means { 31 } like polygon scanner, galvanometer with reflectors, acoustic crystal deflectors, electro-optic prisms/lenses, electric magnets.  
     [0115] The 3 dimensional Image Generator of the type of FIG. 1_A 3  (e 2 ) has multiple beam direction changing means { 52 } such as x, y, z axis control means { 30 , 31 , 32 } polygon scanner, galvanometer with reflectors, acoustic crystal deflectors, electro-optic prisms/lenses, electric magnets. Beam means { 11 } are emitted by the beam emitter means { 4 } such as microwave emitter, radio wave emitter, photon emitter, ion emitter, laser, white color laser, red laser, green laser, blue laser, infrared laser, ultraviolet-ray laser, x-ray laser, combination of those lasers. Beam means { 11 } are focused to a point so that the material means { 18 } such as air, gas, a crystal and crystals emits light and/or particles (photons). By moving this focused point rapidly, the device generates the 3D created image { 2 }.  
     [0116]FIG. 2 shows the example diagrams of 3D image generator means { 1 }. A material means { 18 } such as crystal, gas, and plasma with container means { 19 } with beam direction changing means { 52 } as x-y-z position controller { 30 , 31 , 32 } and their drivers that is contained by inside reflective curved surface with holes { 22 , 23 , 24 }. Beam emitters means { 4 } such as infrared beam emitter emit beam means { 11 } to couple or multiple on a x-y-z position in the material means { 18 } so that the material means { 18 } emit the light or particles means such as photons. Optionally, lens means { 27 } can be added to magnify the 3D core image. Ultrasound scanner { 58 } and a driver { 57 } acquire 3D image data and user interface input device means { 70 } are used to get input signal of a user such as his/her hand movements. In this example, a doctor is acquiring a 3D image of infant in a mother and displaying the infant and the doctor is measuring the size of the infant.  
     [0117]FIG. 3 shows the example diagrams of 3D image generator means { 1 }. The motion such as reciprocating motion and/or rotation with a material means { 18 } such as a layer/layers of crystal, gas, and plasma with/without container means { 19 } with beam direction changing means { 52 } such as acoustic-optic defector, electro-optic prism/lens, polygon scanner, galvanometer with reflector and their drivers, and the beam { 11 } entrance to the material means { 18 } of the motion like reciprocating and/or rotating motion generates the 3D created image { 2 }. The position and/or motion sensor and control means { 79 } detect the position and/or motion of the material means { 18 } send the position and/or motion information to the controller { 57 } as a feedback information and make decision from it.

     [0120]FIG. 1_A 2  shows the example diagrams of the 3 dimensional image generator means { 1 } that create 3 dimensional created image { 2 } using container means { 19 } and material means { 18 } with/without image lifting means { 21 } such as inside reflective curved container means { 22 , 23 , 24 }, reflectors and lens.

     [0156] Operation—FIG. 1, FIG. 2, FIG. 3_A 8   
     [0157] One example of operation is that user can put the 3 dimensional image generator means in front of the objects, creatures such as user himself/herself and record the 3D video image. Then the recorded image can travel though network such as Internet to another 3D image generator means which displays the 3D image recorded either immediately or after some time. User can use this 3D image generator as data transform methods.  
     [0158] Another example of usage is that it can monitor the internal organs, infant in a mother of humans. The 3D data acquired from ultrasound scanner, CT scanner, X-rays can be sent to the 3D image generated by the 3D image generator.

     [0161] Another example of usage is that people can put this device under a table with hole so that displayed 3D image shows up in the middle of table and can use as a general display.  
     [0162] Another way of using this device is that users teach their commands interacting with the invention by language or by visual language such as finger or hand movement. The device talks back to the users if its action is correct or how well done. Users gives response, and the invention learns the commands depending on the response. The invention shows what the invention is thinking by showing to the 3 dimensional virtual images to users. The invention can learn new materials by itself or by users visually looking at new materials or by listening sound, the language and music or by connecting to the information source such as electric dictionary or Internet.
