Abstract
The utility model discloses a mechanical scanning display device which can change axial and radial resolution ratio of displayed three-dimensional images. The mechanical scanning display device comprises a motor, a linear movement mechanism and a luminous device. By utilizing the visual persistence effect, the luminous device in quick rotation can regularly emit light under the control of a control circuit, thereby leading the images to reappear in the actual three-dimensional space.
Description
Technical field
The utility model relates to a kind of three-dimensional display, the visible mechanical scanning display of especially a kind of 360 degree.
Background technology
The principle that the two-dimensional display of existing mechanical type scanner utilization utilization rotation is reproduced 3-D view can be sketched and be: two-dimensional display is periodically rotated, formation has the cylindrical space of certain diameter and height, provide simultaneously and to have occurred successively chronologically, be positioned at the display plane of different azimuth, each plane all can write different two-dimensional signals, when the screen rotating speed is higher than the distinguishable frequency of human eye, and writing information is corresponding with original three-dimensional data, when informational capacity is enough to show the details of original image, the material of screen own becomes invisible, and the two-dimensional image sequence of instantaneous demonstration is because visual persistence effect, will be by the compound 3-D view that is positioned at display space that is perceived as.The essential distinction of considering body three-dimensional display and other three-dimensional display is, the 3-D view of reproduction be 360 ° each to visual, so screen should be 180 ° of visual cosine luminous elements of single face, and double-side is so that show 360 ° of visual informations; When the vertical symmetry axis conllinear of rotating shaft and display screen, can be that single face is luminous, but utilize screen position and the back interior screen position of half swing circle in preceding half swing circle to overlap and display surface accomplishes that towards complementation full-shape is visual.Introduced " the volumetric 3 D display system pixel property based on two-dimentional rotary screen is analyzed " this piece paper on the 33rd volume fourth phase photon journal of publishing in April, 2004, this paper has been introduced and has a kind ofly been utilized visual persistence effect, high-velocity scanning to be in two-dimensional display in the fast rotational, thus in the three-dimensional real space volumetric 3 D display system of reproduced image.But there are two shortcomings in this system: 1, radial direction resolution is non-adjustable.2, need to install a lot of luminous elements on the rotary screen, the high and damage easily of cost of manufacture.
The utility model content
The purpose of this utility model is to provide a kind of mechanical scanning display that can overcome above-mentioned defective, and the radial direction resolution of this mechanical scanning display is adjustable, and cost is low, and failure rate is low.
In order to realize above-mentioned utility model purpose, a kind of mechanical scanning display comprises motor, light-emitting device, it is characterized in that: at least one straight-line motion mechanism is controlled the radial motion of at least one light-emitting device.
A kind of mechanical scanning display comprises motor, light-emitting device, it is characterized in that: at least one straight-line motion mechanism is controlled the radial motion of at least one light-emitting device, the axial motion of a straight-line motion mechanism control light-emitting device.
The utility model compared with prior art has following advantage: (1) image pixel light ejecting device is radially movable, thereby can change the radial distance of adjacent twice luminous corresponding body image vegetarian refreshments, thereby realizes the adjusting of radial resolving power; (2) by reducing the quantity of light emitting pixel point, reduce equipment cost, can reduce failure rate simultaneously.
Description of drawings
Fig. 1 is the schematic diagram of this mechanical scanning display embodiment 1.
Fig. 2 is the schematic diagram of this mechanical scanning display embodiment 2.
Embodiment
This mechanical scanning display comprises: motor 1, linear electric motors 2, a plurality of LED become one dimension light-emitting device 3, motor 4, linear electric motors 5, linear electric motors 6, the some light-emitting device 7 of row.
Embodiment 1
Motor 1 shown in Figure 1 drives linear electric motors 2 and becomes the one dimension light-emitting device 3 of row to move in a circle together with a plurality of LED.Linear electric motors 2 drive a plurality of LED and become the one dimension light-emitting device 3 of row to do radial motion.Like this, a plurality of LED become the one dimension light-emitting device 3 of row under the acting in conjunction of these two kinds of motions, forms one with " based on the volumetric 3 D display system pixel property analysis of two-dimentional rotary screen " identical 3D solid space, and then formation three-dimensional image.
Shown in Figure 2: embodiment 2 has increased linear electric motors 5 makes the light-emitting device 7 can axial motion, like this light-emitting device 7 under the effect of motor 4 circular motion, linear electric motors 5 axial motions, linear electric motors 6 radial motions, form one with " analyzing " identical 3D solid space based on the volumetric 3 D display system pixel property of two-dimentional rotary screen, and then form three-dimensional image.
Be appreciated that the linear electric motors that use in above-mentioned two kinds of execution modes can change any straight-line motion mechanism into, as pinion and rack, ball-screw nut mechanism etc.Light-emitting component in the light-emitting device can be a led light source itself, also can be optical fiber.With same mounting means several being installed again comprises linear electric motors 2 and becomes the device of one dimension light-emitting device 3 of row or the device that comprises linear electric motors 6 and some light-emitting device 7 can show 3 D stereoscopic image equally with a plurality of LED.
A plurality of LED that some light-emitting device 7 among the embodiment 2 also can change among the embodiment 1 become an one dimension light-emitting device 3 that is listed as.
Again several a plurality of LED that install become the one dimension light-emitting devices 3 of row also can become 3-D view more on 2 in embodiment 1 cathetus motor; Again on 6 in embodiment 2 cathetus motors more some spots light-emitting devices 7 are installed also can be become 3-D view.
