Produced by the rotation or translation of screen, voxel is activated on the surface of emission in the inswept imaging space of screen.After voxel activation
Effective time be limited, it is therefore desirable to each voxel for constantly refreshing in imaging space.So, the motion frequency of screen will
It is enough fast, the stereo-picture of stable three-dimensional body could be generated.Because swept-volume Display Technique is next by the periodic motion of screen
Imaging space is constituted, high movement velocity can produce a series of mechanical problem, the stability and display unit of mechanical part
Service life, the noise of mechanical part and vibration, impact of the mechanical part to the portability of display unit, system operatio in addition
Upper inevitable error brings big mechanical shock and big acceleration for display unit.Screen size and weight are larger, this
Plant and show the structural constraint development of true three-dimension display technlolgies.
The content of the invention
To solve the defect that prior art is present, the purpose of this utility model is to provide a kind of rotating lens ultrashort burnt throwing
Shadow machine, compact conformation, rotating lens is light and handy, rotates flexible, easy to control, is capable of achieving in the case where whole body is motionless ultrashort
Jiao's rotation projection, in annular Mu Shang projection images.
For achieving the above object, the technical solution adopted in the utility model：The rotating lens ultra short focal projector, with light
Learn optical projection system, it is characterised in that：The optical projection system includes projection lens, is provided with inclined above projection lens
Plane mirror, is provided with non-spherical reflector above plane mirror opposite side, the plane mirror and aspherical anti-
Penetrate mirror to be fixed on rotation platform, rotation platform described in Motor drive rotates centered on projection lens optical axis, and projection lens is penetrated
The light for going out Jing plane mirrors and non-spherical reflector reflective projection successively.
The non-spherical reflector is concave surface non-spherical reflector or convex aspheric surface speculum.
The rotation projection ultra short focal projector is used for real tri-dimension and shows projection.
The motor is servomotor or program control motor, and body position sensor detects orientation angles residing for human body, transmission signal
To electric machine controller, the angle of motor controller controls motor rotation, realize that scene follows the trail of projection.
Counterweight block structure is provided with the rotation platform, rotation platform high-speed smooth rotation is made.
The rotation projection ultra short focal projector is used for entertainment environment and projects or for rotating projection lamp.
The rotation projection ultra short focal projector can be used for the laser radar of 700nm to 2500nm wavelength.
The light source of the optical projection system is pure LASER Light Source, LED/light source, laser add phosphor source or laser to add
LED adds fluorescent material mixing light source.
Using the beneficial effect of above-mentioned technical proposal：The rotating lens ultra short focal projector is in the motionless situation of whole body
Ultrashort burnt rotation projection is capable of achieving down, can be in annular Mu Shang projection images, it can also be used to tripleplane.Real tri-dimension shows skill
Art refers to by a 3D display directly display 3-D view that observer need not wear any auxiliary equipment and achieve that
Full what comes into a driver's, multi-angle, many people observe three-dimensional body image simultaneously, so that three-dimensional body shows the existing psychological depth of field, and
There is physical depth, more conform to actual conditions.
Present Three-dimensional Display generally uses flat-panel screens stimulated three-dimensional image or using the auxiliary of 3D glasses etc
Help equipment.Such display mode lacks physical depth, and use condition is also harsher.The Basic Mechanism of true three-dimension display technlolgies
To be imaged at space set point (x, y, z) place, each imaging point be the most basic unit of three-dimensional imaging-be referred to as body
Vegetarian refreshments, a series of tissue points just define real 3-D view in actual three dimensions.It has real physics depth
Degree, at the same it is easy to use, without the need for special auxiliary equipment.
Swept-volume technology is mainly used in the display of dynamic object.In the art, a string of two dimensional images are projected to one
In rotation or mobile screen, while the speed that cannot be perceived with observer of the screen is in motion because the persistence of vision of people from
And three-dimensional body is formed in human eye.Therefore, it is capable of achieving the very three-dimensional of image using the display system of this stereo display technique
Show, the light beam of different colours is projected on display medium by light deflector in system so that medium embody it is abundant
Color.Meanwhile, this display medium can allow light beam to produce discrete visible point of light, and these points are exactly voxel, corresponding to three-dimensional
Any point in image.One group of group voxel is used for setting up image, and observer can be from any viewing point to this true 3-D view.
In swept-volume display system, the screen in structure imaging space is made up of two parts：For generating the surface of emission and the offer of voxel
The supporter of mechanical support.So the screen of motion is the combination of the surface of emission and supporter.Voxel is activated in the surface of emission, then
As the cycle movement of screen constitutes imaging space, so as to obtain true Three-dimensional Display.
The motor is servomotor or program control motor, and body position sensor detects orientation angles residing for human body, with human body
Rotation, transmit a signal to electric machine controller, the angle of motor controller controls motor rotation makes the image of corresponding conversion all the time
It is projected in face of people, realizes the scene projection such as emulation interaction.The rotation projection ultra short focal projector is used for public place of entertainment ring
Border projection is used, and can in the environment rotate projection video picture, magnificent mansion.In scientific visualization, Flight Vehicle Design, emulation,
Virtual training system, CAD/CAM fields, architectural design, home entertaining, commodity show, the field such as interactive 3D internet exchanges
There is good application prospect.
