Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-9, the present invention provides a technical solution: a microlens set capable of realizing light field duplication transformation operation, comprising a prism 1001, a prism group 101, a prism bar A1 and a prism bar B2; the long side 1002 of two prisms 1001 paste mutually and form prism group 101, a plurality of prism group 101 end to end constitutes prism strip A1, prism strip B2 is provided with to the both sides of prism strip A1, and a plurality of prism strips A1 and prism strip B2 interval sets up and forms microlens set 3, there is the straight line that the plane intersection that at least three face was located in microlens set 3 gets parallel each other, and prism strip A1 and prism strip B2 are responsible for the spotlight of X direction and Y direction respectively, and consequently prism strip A1 and prism strip B2's interval sets up can effectively improve the definition of formation of image, of course, prism strip A1 and prism strip B2 are not in the coplanar, also can realize formation of image, and when prism strip A1 and prism strip B2 were not in the coplanar, only need satisfy in lens set 3 that there is the straight line that the plane intersection that at least three face was located is parallel each other, at this moment prism 1001 is also can be formed into images for the intersection of projection department that prism A1 and prism strip B2, and N=3, prism 1001's cross-section is the isosceles triangle or arbitrary one kind of isosceles triangle or two kinds of integrated into one piece or combination of lens in the isosceles triangle shaping.
Wherein the reflecting surfaces of the prism strips A1 and B2 are vertically or non-vertically arranged.
The microlens set 3 is made of a transparent material or a colored transparent material, and when the microlens set 3 is made of a transparent material, the transmittance is optimal at this time, and of course, when the microlens set is made of a colored transparent material, light with a specific color can be filtered out, so that specific requirements are met.
Wherein, the material of the micro lens set 3 is any one or the combination of a plurality of solid forms of glass, plastic and transparent liquid.
Wherein the micro lens set 3 is any one or the combination of a plurality of planes, curved surfaces or different surfaces.
The long side 1002 and the prism 1001 are integrally formed or the surface of the long side 1002 is plated with a reflective material, and the surface of the long side 1002 is plated with a reflective material, so that the reflective material can further improve the light field replication efficiency of the microlens set, and when the film is plated, light refraction exists in the light field and light reflection exists in the light field, so that the imaging effect is better.
Wherein, the distance between the prisms 1001 is 1 nanometer to 0.5 millimeter.
The technology is also specifically divided into two technical schemes of a limited focus technology and an infinite focus technology;
the finite focus means that the finite number of focuses is used for realizing the reflection or refraction of a certain object through a tiny lens set;
infinite focus means that there are innumerable focuses that are reflected or refracted by an object through a collection of tiny lenses.
Basically in practice, from a microscopic point of view, the current theory mainly considers that the basic units of the world are not subdivided, so that the implementation will also tend to be all limited focus techniques;
while the universe is infinite, the number of foci will also approximate infinity from a macroscopic point of view, and the extremes depend on a limited and infinite understanding of the world by humans.
In practical production, the technology is almost limited focus.
Optical path principle: in the technical scheme of the scheme, a plurality of limited micro-lens sets are adopted, each micro-lens can refract light, therefore, after the micro-lenses form the set, the size of a single micro-lens is small enough, the full replication of the light can be realized, and after a long-side surface is plated with a reflecting film, the prism is closer to the prior art, the light can be refracted by the prism, the reflection of the light can be realized after the film plating, so that the imaging effect is improved, but the process difficulty and the yield are increased, the light path replication can be realized without the film plating, as shown in fig. 4, the micro-prisms x1, x2 and x3. are arranged, when the light is emitted from the point A, the light is emitted to the point A according to the refraction principle after passing through the micro-prism x1, obviously, the light passing through the point X2 is emitted to the point A, and repeatedly, the light passing through the micro-prisms x1, x2 and x3. are converged to the point A, and the diameter D of the convergence range of the center point A is also reduced along with the reduction of the micro-prism D. In the first place, the prism arrays y1, y2, y3...yn perpendicularly intersect with the prism arrays x1, x2, x3...xn as shown in fig. 6, 7 and 8, and then the light emitted at a is converged toward a through the prism arrays y1, y2, y3...yn, so that one of the expression forms described in the present technology can be obtained. Fig. 6 is a top view, and an intersection portion of the top view X array and the Y array can converge light rays in two perpendicular directions. In which, as shown in fig. 8, the light rays emitted from the lower side are refracted by the prism units in two perpendicular directions and then converged at the same distance on the other side.
Working principle: the unit of the micro array is an isosceles right triangular prism which is approximately equivalent, and meanwhile, different prisms can be replaced according to different requirements in the actual manufacturing process. The isosceles right triangular prism has a special characteristic that the isosceles right triangular prism can realize total reflection, the characteristic can be used for replacing the isosceles right triangular prism in a plurality of places needing plane mirrors, the thought is provided for well understanding that the tiny plane mirrors in the micro-mirror array in the prior art can be replaced by the isosceles right triangular prism, the technology can be used for realizing the overlapping of the functions of the technology, the long side surface coating of the triangular prism can be closer to the prior art, but the coating or the non-coating can be carried out in the specific implementation process, meanwhile, the patent application can be used for replacing the triangular prism, the four prisms, the penta prism and the like, and the isosceles right triangular prism or the isosceles right triangular prism can also be used for carrying out the machining process such as chamfering and rounding or the like, and the necessary or unnecessary post-treatment process is also included in the scope of the improvement of the technology.
