Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment one
nullPresent embodiments provide a kind of multisection type scattering wheel，As shown in Figure 2，Including transparency carrier 2，This transparency carrier 2 is divided at least one sector region 20，And sector region 20 is divided at least one fanned partition，Such as sector region 20 is divided into four fanned partitions 1～4，These fanned partitions are respectively provided with the scattering layer being positioned at transparency carrier 2 surface，Wherein，The astigmatism angle of the scattering layer in different fanned partitions in same sector region is different，The such as astigmatism angle of the scattering layer of fanned partition 1～4 is the most different，And，Owing to the fanned partition in same sector region is arranged in order，The ordering of the fanned partition in different sector regions is identical，Therefore，When scattering wheel rotates，Multi-angle can be realized by the fanned partition of different astigmatism angles to change，By have the fanned partition of identical astigmatism angle be repeated to realize many frequencys change，And then speckle can be eliminated by light superposition in time domain.
In the present embodiment, transparency carrier 2 is circular substrate, and all fanned partitions on transparency carrier 2 constitute the annulus of closing, in order to the present embodiment provide multisection type scattering wheel along a direction rotate time, incident beam is behind fanned partition, it is possible to realize the astigmatism of different angles.
The multisection type scattering wheel that the present embodiment provides is along the sectional drawing in A direction as it is shown on figure 3, include transparency carrier 2 and be positioned at the scattering layer 21 on transparency carrier 2 surface, and wherein, the material of scattering layer 21 can be to scatter powder, it is also possible to for glue, such as silica gel.Additionally, the transparency carrier 2 in the present embodiment is macromolecular material plate, such as PC (Polycarbonate, Merlon) plate and acrylic board, and a surface of this transparency carrier 2 has scattering layer, but the present invention is not limited to this.
When scattering layer 21 is for scattering powder, as it is shown on figure 3, incident beam through uneven medium i.e. after ups and downs scattering particles, the original direction of propagation can be deviateed toward propagation of scattering from all directions, scattering of light i.e. occurs, it is achieved the diffusion of light beam.Wherein, the size of beam spread angle is relevant with factors such as the thickness of the refractive index of scattering particles, granular size, concentration and coating.
It is to say, there is following relation in the scattering refractive index of powder, granular size, concentration and coating layer thickness and the astigmatism angle of scattering layer: 1, scattering powder concentration is the highest, and astigmatism angle is the biggest；2, scattering layer is the thickest, and astigmatism angle is the biggest；3, scattering powder particles is the thinnest, and light-dispersing effect is the best；4, scattering powder refractive index is the least, and preferably closest with the refractive index of transparency carrier, the reflection loss of scattering layer is the least.
Based on this, the present embodiment can form the astigmatism coating with different astigmatism angle by controlling the scattering refractive index of powder, granular size, thickness and concentration in different fanned partitions.In the present embodiment, scattering powder can include aluminium oxide, barium sulfate, glass dust and silica flour etc., when selecting the scattering powder making scattering layer, in view of refractive index problem, silica flour that preferred index is close with transparency carrier and glass dust, the scattering powder that preferred granule is tiny in silica flour and glass dust the most again.
The multisection type scattering wheel provided due to the present embodiment is not to be spliced into by multiple fanning strips, therefore, solves the existing multisection type scattering wheel problem that dimensional requirement is strict, concatenation is difficult and firmness is poor to fanning strip.Further, the multisection type scattering wheel of the present embodiment offer also has the beneficial effect eliminating speckle, and its method eliminating speckle is roughly divided into two kinds: a kind of is that the coherence weakening light source by scattering the volume scattering of powder eliminates speckle；Another kind is the transformation by the many frequencys of multi-angle, carrys out superposition from time domain and eliminates speckle.
By the principle of the volume scattering dissipation speckle of scattering powder as shown in Figure 4.Volume scattering refers to that incident beam, after intensive random medium (such as scattering particles), deviates the original direction of propagation process toward surrounding generation multiple scattering, and wherein, the light path that different light is passed by after multiple scattering is different.Such as, the light path of incident ray 1 process is the longest, not only there is scattering to all the winds in numerous scattering particles faces in it, also in the contact interface experiences total internal reflection with air, it is to say, multiple scattering extends the propagation path of light wave, cause the delay of certain time, if the time postponed is equal with the coherence time of light source or exceedes coherence time of light source, then can eliminate speckle.
By the principle rotating elimination speckle of multisection type scattering wheel it is: the phase place being applied in due to each point on different time screen is different, therefore, incide the light phase difference on screen otherwise varied, such that it is able to produce different speckles, within the time of integration of human eye, after the incoherent speckle particle superposition that these different times produce, the contrast of speckle can be reduced.
As it is shown in figure 5, owing to multisection type scattering wheel 50 has multiple different astigmatism angle, therefore, incident beam, after the multisection type scattering wheel 50 rotated, to have the beam exit of different diffusion, and is radiated on the diverse location of screen 51.Owing to each point on screen 51 has different amplitudes and phase place, therefore, the light beam of multisection type scattering wheel 50 outgoing through different propagation paths after different time arrives the diverse location on screen, the speckle formed can be overlapped, over time and space such that it is able to effectively weaken speckle.
The multisection type scattering wheel that the present embodiment provides, owing to transparency carrier has multiple sector region, and each sector region includes again the multiple fanned partitions with different astigmatism angle, therefore, when multisection type scattering wheel rotates, it is capable of the circulation of many frequencys of many astigmatism angle, add the frequency of angular transformation, dissipation speckle better, and, the multisection type scattering wheel provided due to the present embodiment is not to be spliced into by multiple fanning strips, therefore, solve existing multisection type scattering wheel strict to the dimensional requirement of fanning strip, the problem that concatenation is difficult and firmness is poor, and the simple in construction of this multisection type scattering wheel, with low cost.
Embodiment two
The structure of the multisection type scattering wheel that multisection type scattering wheel and the embodiment one that the present embodiment provides provides is substantially the same, its difference is, the multisection type scattering wheel only one of which surface that embodiment one provides has scattering layer, and two surfaces of the multisection type scattering wheel that the present embodiment provides are respectively provided with scattering layer.
As shown in Figure 6, when requiring that multisection type scattering wheel has bigger astigmatism angle, i.e. require when concave-convex surface inclination angle is the biggest, can be coated with on two surfaces that transparency carrier 2 is relative scattering bisque, the multisection type scattering wheel that the present embodiment provides includes transparency carrier 2, two surfaces of this transparency carrier 2 are respectively provided with sector region, fanned partition and are positioned at the scattering layer 20 and 21 of fanned partition, and equally, in same sector region, the astigmatism angle of the scattering layer of different fanned partitions is different.Preferably, the transparency carrier in the present embodiment is PC plate.
The multisection type scattering wheel that the present embodiment provides, by the two-sided the lowest curvature of scattering process, the light-dispersing effect at the big inclination angle of one side can be realized, and, the operation of this multisection type scattering wheel blade coating scattering layer is also very convenient, and on the scattering layer of low curvature, plated film is also easy to.
Certainly, the present invention is not limited to this, in other embodiments, as shown in Figure 7, transparency carrier 2 can also have sector region, fanned partition and be positioned at the scattering layer 21 of fanned partition in a surface, and another surface has reflecting layer 23, thus can form reflection-type multisection type scattering wheel.
As shown in Figure 8, incident ray 80 is when reflection-type multisection type scattering wheel, can occur to scatter many times at scattering particles layer, and there are two secondary reflections at scattering particles layer 21 and reflectance coating 23, the Gaussian distribution feature of light is so changed through scattering many times and multiple reflections, emergent ray 81 is made to become the equally distributed flat top beam of a branch of light intensity, wherein, flat top beam refers to the light beam at regional optical power detection, it is conducive to the homogenization of picture, is also a kind of mode weakening speckle contrast.
But, owing to the scattering particles in reflection-type multisection type scattering wheel has the effect of volume scattering, incident ray can occur multiple scattering, and each beam spreading is penetrated or the light that reflects have passed through different paths, therefore, the outgoing beam finally given not is lambert's flat top beam, but non-lambertian flat top beam as shown in Figure 8.For lambert's flat top beam, the angular region of non-lambertian flat top beam is less, and therefore, the beam utilization of the reflection-type multisection type scattering wheel that the present invention provides is higher.
The multisection type scattering wheel that the present embodiment provides, owing to transparency carrier has multiple sector region, and each sector region includes again the multiple fanned partitions with different astigmatism angle, therefore, when multisection type scattering wheel rotates, it is capable of the circulation of many frequencys of many astigmatism angle, add the frequency of angular transformation, dissipation speckle better, and, the multisection type scattering wheel provided due to the present embodiment is not to be spliced into by multiple fanning strips, therefore, solve existing multisection type scattering wheel strict to the dimensional requirement of fanning strip, the problem that concatenation is difficult and firmness is poor, and the simple in construction of this multisection type scattering wheel, with low cost.
Embodiment three
The structure of the multisection type scattering wheel that multisection type scattering wheel and the embodiment one that the present embodiment provides provides is substantially the same, its difference is, the transparency carrier of the multisection type scattering wheel that the present embodiment provides is diffuser plate, and this diffuser plate has the concavo-convex surface of relative and a plane, in addition, the material of the scattering layer in the present embodiment is scattering powder, wherein, as it is shown in figure 9, scattering powder coating 26 may be located at the male and fomale(M&F) of diffuser plate 25, the plane of diffuser plate 25 can also be positioned at, as shown in Figure 10.
When scattering the female that powder fills diffuser plate male and fomale(M&F), it is possible to decrease the curvature of diffuser plate male and fomale(M&F), i.e. reduce its astigmatism angle.When scattering that powder concentration is higher, thickness is thicker, scattering powder coating forms new concavo-convex relief fabric, such that it is able to obtain bigger astigmatism angle further through self scattering particles after having filled diffuser plate crowning.Therefore, the male and fomale(M&F) at diffuser plate coats scattering powder and the astigmatism angle of diffuser plate can be decreased or increased.When coating scattering powder in the plane of diffuser plate, astigmatism angle can be regulated by scattering powder coating, there is provided certain astigmatism angle by the concavo-convex relief fabric of diffuser plate self simultaneously, decrease the light efficiency loss that the volume scattering of scattering powder causes, improve light efficiency.
Certainly, the present invention is not limited to this, in other embodiments, the material of scattering layer can also be glue, as shown in figure 11, sector region, fanned partition and be positioned at the scattering layer i.e. glue 24 of fanned partition and may be located at the male and fomale(M&F) of diffuser plate 25, it is also possible to be positioned at the plane of diffuser plate 25, as shown in figure 12.
When coating glue at the crowning of diffuser plate, glue is laid in the crowning of diffuser plate, the convex-concave surface making diffuser plate becomes opposed flattened, and the scattering process of the concave-convex surface fluctuating particle that such incident beam is subject to will weaken, thus plays the effect reducing diffuser plate astigmatism angle.
In the present embodiment, by selecting the glue of different refractivity and the scattering layer of different-thickness can be formed, control the degree that astigmatism angle reduces, thus obtain different astigmatism angles.Wherein, the coating of glue is the thickest, and its scattering degree is the lowest, and the astigmatism angle obtained is the least；The refractive index of glue is the lowest, transmitance is the highest, and reflection loss and absorption loss water are the least, and light-dispersing effect is the best.Based on this, the glue in the present embodiment is preferably silica gel.
Compared with the mode of coating scattering powder, the mode efficiency of coating glue is higher.On the transparent substrate during coating scattering powder, under the effect of scattering powder body scattering, light not only can occur forward scatter that backscattering also can occur, cause light loss of efficiency, therefore, coating scattering powder is typically only capable to reach the light efficiency of more than 70%, and cementing can reach the light efficiency of more than 90%.
When flat coating glue at diffuser plate, the glue of plane can increase the astigmatism angle of diffuser plate.Glue layer non-fully plane due to coating, but there is a certain degree of concaveconvex structure, therefore, incident beam can occur refraction and the scattering of light beam in glue face, that is, light beam can occur the deviation of certain angle after glue layer, adds the scattering effect that its small concaveconvex structure brings, it is possible to achieve the effect of expanded light beam angle.Equally, also can obtain different astigmatism angles by the refractive index and thickness controlling glue at flat coating glue, but for relative crowning, plane gluing is less for the range of accommodation of angle.
Based on this, the multisection type scattering wheel that the present invention provides can be any of the above-described kind of multisection type scattering wheel, it is also possible to the scattering wheel with different angles prepared for multiple aforesaid way combination in any.Owing to transparency carrier has multiple sector region, and each sector region includes again the multiple fanned partitions with different astigmatism angle, therefore, when multisection type scattering wheel rotates, it is capable of the circulation of many frequencys of multi-angle, add the frequency of angular transformation, dissipation speckle better, and, the multisection type scattering wheel provided due to the present embodiment is not to be spliced into by multiple fanning strips, therefore, solve existing multisection type scattering wheel strict to the dimensional requirement of fanning strip, the problem that concatenation is difficult and firmness is poor, and the simple in construction of this multisection type scattering wheel, with low cost.
