Example Embodiment

[0049] Example 1:
[0050] This embodiment provides a method of realizing the effect of a fluent pattern projection, which causes a distortion effect by making the image surface projection imaging to generate a distortion effect by causing the imaging material to the projection position of the image surface, and dynamically adjust the magnification of different positions. The rate changed its distortion effect, even if dynamic optical distortion occurs on the image surface, the imaging is present in the projection of the image plane exhibits a fluctuation.
[0051] The magnification of the dynamic adjustment of the different locations is specifically; the magnification of a certain location is changed to the amplification rate of adjacent positions.
[0052] The change in magnification can cause a distortion state that occurs on the image surface projection, and in this scheme that causes the image surface projection to deform the image plane projection, and then dynamically adjust the magnification of each position, The extent of the deformation is changed.
[0053] For example, the position of the portion of the image plane occurs is abomicous, and the portion where the portion is negative, the position of the positive distortion is alternately arranged, and the position of the negative change is arranged, and the position of the position of the positive distortion is continuous. The smooth transition, continuously changing the magnification of the distortion position, then dynamic changes in the distortion state of the corresponding position, the projection effect at this time will show dynamic fluctuations on the entire image surface, and the effect is similar to the graphical picture in the clear water. The display effect of the picture of the underwater surface is observed by the surface of the water surface in the water fluctuation.
[0054] It should be noted that there is no connection between the regions of the regular distortion and the negative distortion, and the distortion state can also be adjusted in other embodiments to adjust the distortion state, that is, part of the portion The region occurred in the region, and the regions where the region between the region and the region of the region and the negative distortion occurrence.
[0055] Alternatively, it is also possible to use only the discontinuous transition between the projections in the image surface, which occurs between the region, in the region where the orthodontic change or the negative distortion occurred.
[0056] The projection effect of dynamic fluctuation can be achieved by optically optimization, and its use of classic geometric imaging principles and human eye visual temporarily, through dynamically changed the image distortion state, thereby changing the optical distortion of the local image plane and The similarity of the object, which in turn achieves a picture dynamic effect of regular fluctuations while maintaining the sharp loss of the projection screen.

Example Embodiment

[0057] Example 2:
[0058] figure 1 The imaging principle of a projection system imaging of the static pattern projection is shown in the present scheme embodiment. figure 2 The overlapping state of the projection effect of the optical distortion in the present scheme, the optical distortion, and the projection effect of the optical distortion. like figure 1 , 2 As shown, the present embodiment provides a projection system that implements the static pattern projection showing fluctuation effect, which increases the disturbance sheet lens based on the existing optical projection apparatus, and the structural design of the disturbance lens 4 and the disturbance lens 4 and the imaging. 3 The relative positional change is controlled to the imaging optical distortion state of the image surface 14.
[0059] In this embodiment, the material is formed as an example, figure 2 The projection effect of the rectangular imaging in the rectangular imaging occurs, the solid line and the dotted line are the projection effect after the optical distortion occurs, and the overlapping image 15 can be seen from the three images, figure 2 Two static distortion images are shown in this scheme to realize the dynamic transition of the image from the solid line projection state to the dotted projection state, thereby generating a dynamic fluctuation projection effect on the image plane.
[0060] image 3 A structural diagram of a projection system that is fluent on a fluent pattern projection. like image 3 As shown in the present embodiment, the present invention specifically includes a light source 1, a concentrating mirror group 2, an imaging 3, a spanning lens 4, and a projection lens group 5 in which the optical path is sequentially provided, wherein the disturbance lens 4 is facing the imaging 3 One side surface is provided with a plurality of curved convex surfaces, and the screening lens 4 is provided by the arcuate convex surface 6 can make the projection of the imaging 3 generate optical distortion, and then relatively moved between the disturbance lens 4 and the imaging 3. Adjust the magnification to change the distortion state, the imaging 3 can cause dynamic disturbance of the projection of the image plane 14.
[0061] Where the concentrating mirror group is optionally a convex lens in which a reflective cup or a plurality of convex lenses is combined, a condensing mirror group formed by a plurality of convex lenses in this example. The light source uses an LED light source, and the concentrating mirror group gives the light emitted by the LED light to form a beam, and the beam angle of the beam is 15 ° in the present embodiment; the light-expand surface of the concentrating mirror group and the imaging The distance is 10 ㎜.
[0062] In this embodiment, the projection lens group is equipped with a fixed focus lens, its focal length is 100 ㎜.
[0063] The relative movement between the disturbance lens 4 and the imaging 3 described in this scenario includes the disturbance lens 4 that is always located on the optical path between the imaging 3 and the projection lens group 5, and projected on the image surface 14 on the image plane 14 The rate is affected, and the disturbance lens 4 is removed from the optical path between the imaging 3 and the projection lens group 5, the projection system performs a conventional static projection.
[0064] Figure 4 A structural diagram for the disturbance lens, Figure 5 for Figure 4 The cross-sectional enlarged view of the disturbance lens is shown. like Figure 4 , 5 As shown, the disturbance lens 4 in this embodiment is formed of a plurality of curvature radius R between 6-150 ㎜, a radical convex surface 6 linear array is formed in a transparent glass surface, said The height H of the curved convex surface 6 is continuously changed between 0.05-1.5. Excessive radius of curvature will increase the light deflection capability, increase the aberration, and severely change the image similarity, so that the image plane becomes excessive distortion, and the R value is too large and the plane will make the optical distortion of the imaging system No changes have changed, the effect of image versus fluctuations will not be possible. The overall disturbance lens 4 is rounded, and its curved convex surface 6 is disposed toward the formatter 3, and the arcuate convex surface 6 is disposed toward the imaging 3 to ensure that the discharging lens 4 itself is not due to distance orchard. The imaging quality of the lens group 5 produces a significant impact. It is between 0-6 ㎜, and in this example, the distance between the arcuate convex surface 6 and the imaging 3 is preferably 2 ㎜, and the lens aberration is exceeded. An unacceptable significant impact, which affects the clarity of the picture.
[0065] A relative movement of the disturbance lens 4 and the imaging 3 in this embodiment is a specific manner of the disturbance lens 4 to rotate around the axis of the optical axis.
[0066] Specifically, the light source 1 is used in this embodiment employ an LED light source, the projection system that implements the static pattern projection showing the effect of the fluctuation, including the relative fixed set LED light source, the condenser set 2 imaging 3 and the projection lens group 5, A disturbance lens 4 is provided between the projection lens group 5 and the imaging 3, the disturbance lens 4 is circular, and the rotary center is fixed to the power output shaft of the drive motor 7, the power of the drive motor 7 The axis of the output shaft is parallel to the optical axis of the projection system, but does not connect with the optical axis.
[0067] In a state where the drive motor 7 does not rotate, the fixed position of the disturbance lens 4 is between the imaging 3 and the projection lens group 5, and the magnification of the different positions of the imaging 3 is fixed, and the image is static distortion effect. .
[0068] When the drive motor 7 is rotated, the drive motor 7 drives the disturbance lens 4 to rotate, and the different positions on the disturbance lens 4 are different from the imaging 3 and the projected lens group 5, and the disturbance lens 4 constantly moves. The magnification is constantly changing, so that the magnitude of the image surface 14 projected the distortion, the fluctuation projection effect of still images can be realized.

[0071] Specifically, the disturbance lens 4 is formed by a plurality of curvature radius R between 6-150 ㎜, is formed in a transparent glass surface. The height H of the arc-shaped convex surface 6 is continuously changed between 0.05-1.5. The arcuate convex surface 6 of the disturbance lens 4 is disposed toward the formation 3, and its curved convex surface 6 is between the shortest distance of the imaging 3 at 0-6 ㎜, in this embodiment, 6 ㎜ is preferred.
[0072] The difference from the second embodiment is that the structure and parameters of the light source, the concentrate mirror group, and the projection lens are different, and the concentrating mirror group is a reflective cup.
