Description

Technical Field

[0001] This utility model relates to optical device technology, specifically to a dispersive focusing component. Background Technology

[0002] In the current field of optical equipment and vision assistance technology, especially in applications requiring high-precision visual positioning and real-time distance judgment, such as industrial alignment, medical positioning, and virtual reality interaction, the demand for highly integrated and miniaturized optical components is becoming increasingly urgent. These components need to achieve two core functions within extremely limited space: first, to provide a clear and stable visual center reference to assist users in pupil self-localization; and second, to achieve rapid distance judgment without the need for external calibration through optical feedback.

[0003] Traditional optical implementations often employ a kaleidoscope-like structure based on multi-mirror reflection. This structure generates symmetrical and visually stunning patterns through reflection from three mirrors, possessing considerable visual appeal. However, such structures are generally large in size and have complex optical paths, making them difficult to integrate into modern compact devices. Furthermore, existing technologies are mostly single-function, unable to combine multiple functions such as dispersion enhancement, visual guidance, center positioning, and ranging within a single miniature optical structure. This limits their effectiveness in visual assistance scenarios requiring high visual appeal, rapid response, and intuitive interpretation. Utility Model Content

[0004] The purpose of this invention is to provide a dispersive attention component to solve the problems of large size, single function and low integration of existing visual positioning devices, which make it difficult to achieve integrated application of visual attraction and precise optical guidance in miniaturized devices.

[0005] To achieve the above objectives, this utility model provides a dispersive attention component, comprising:

[0006] The dispersive body is made of transparent material. It has a first light inlet and a first light outlet. The first light inlet allows incident light to enter the dispersive body. The outer surface of the dispersive body is coated with a reflective coating layer except for the first light inlet and the first light outlet.

[0007] The eyepiece is made of transparent material. The eyepiece has a second light inlet and a second light outlet. The outer surface of the eyepiece is coated with a reflective coating layer except for the second light inlet and the second light outlet.

[0008] The second light inlet receives the light emitted from the first light outlet;

[0009] The peripheral surface of the object of attention has a multifaceted structure, and at least one of its surfaces has markings for observation.

[0010] Compared with the prior art, the dispersive attention component provided by this utility model can efficiently realize the dispersion, spectral storage, multipath modulation and directional emission of incident light through the setting of the dispersive body and attention body. It not only significantly enhances the visual appeal and color richness of the emitted light, but also allows the observer to obtain a stable and clear center positioning reference and intuitive and accurate visual distance feedback. It effectively solves the problem in the prior art that it is difficult to take into account visual guidance, positioning and distance measurement functions in a limited space.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] As attached Figure 1 To be continued Figure 8 As shown, this utility model provides a dispersive attention component, comprising:

[0024] The dispersant 100 is made of transparent material. The dispersant 100 is provided with a first light inlet 101 and a first light outlet 102. The first light inlet 101 allows incident light to enter the dispersant 100. The outer surface of the dispersant 100, except for the first light inlet 101 and the first light outlet 102, is coated with a reflective coating layer.

[0025] The eyepiece 200 is made of transparent material. The eyepiece 200 is provided with a second light inlet 201 and a second light outlet 202. The outer surface of the eyepiece 200, except for the second light inlet 201 and the second light outlet 202, is coated with a reflective coating layer.

[0026] The second light inlet 201 receives light emitted from the first light outlet 102;

[0027] The peripheral surface of the object 200 has a multifaceted structure, and at least one of its surfaces has markings for observation (not shown in the figure).

[0028] Specifically, after the incident light enters the dispersive element 100 through the first light inlet 101, the light undergoes multiple reflections and refractions inside the reflective coating layer due to the reflective coating layer on the outer surface of the dispersive element 100. The white light is decomposed into a polychromatic spectrum and temporarily stored inside the dispersive element 100. Part of the light exits through the first light outlet 102 and enters the second light inlet 201 of the attention object 200. Similarly, the outer surface of the attention object 200 is coated with a reflective coating layer. After further reflection and refraction through the multifaceted structure inside the attention object 200, the light finally exits through the second light outlet 202 at a certain divergence angle. When the observer receives the outgoing light through the pupil, they can see the symmetrical pattern or stripes formed by the markings. The central pattern corresponds to the farthest observation distance, and the outer pattern corresponds to the closer distance, thus realizing the functions of visual positioning and distance determination. At the same time, due to the superposition of the dispersion effect and multifaceted reflection, the outgoing light presents a colorful visual effect, significantly enhancing visual appeal and psychological attention.

[0029] The first light outlet 102 of the dispersive element 100 and the second light inlet 201 of the luminous element 200 are connected to each other by means of optical bonding, mechanical snap-fit ​​or threaded connection to ensure the continuity of the optical path and reduce light energy loss at the interface.

[0030] As attached Figure 7 and attached Figure 8As shown, the shape of the second light outlet 202 can be designed according to actual optical needs, such as being constructed as a planar, concave spherical, or convex spherical shape. When it is set as a concave spherical shape, the structure is equivalent to a concave spherical lens, which can modulate the outgoing behavior of light rays inside the object 200. Specifically, when light rays from the side of the object 200 that were originally unobservable due to exceeding the critical angle strike the concave spherical structure, under the condition that the medium angle is less than the critical angle of total internal reflection, the light rays undergo large-angle refraction, and their outgoing direction is adjusted and enters the range that the human eye can receive, thereby turning the originally invisible area into a visible one and significantly expanding the effective observation area. The propagation path of the light rays can be specifically calculated and designed according to Snell's Law. For example, when the refractive index n1 of the transparent medium used in the object 200 is 1.49, and a ray of light is incident from inside the medium at an angle i (the angle with the normal, for example, 38.05°) onto the concave spherical light-emitting surface, the angle of refraction in air, r, can be calculated using the refractive index formula n1×sin(i)=n2×sin(r), where n2 is the refractive index of air (taken as 1.00); substituting the values, we get:

[0031] sin(r)=(n1×sin(i)) / n2=(1.49×sin(38.05°)) / 1.00≈0.919, that is, the angle of refraction.

[0032] r≈arcsin(0.919)≈66.69°; After the refracted light is emitted at a large angle, its backward extension can fall into the receiving range of the human eye's pupil, thus turning the light that was originally in an unobservable area into something visible to the user, significantly expanding the effective field of view.

[0033] In one embodiment of this utility model, a lens (not shown in the figure) is added to the side of the second light outlet 202 near the pupil of the human eye;

[0034] Specifically, the lens can be either a convex or concave lens, and is fixed by optical adhesive bonding, mechanical snap-fitting, or integral molding with the exit of the focus object 200. When diverging or converging light rays emitted from the second light exit 202 pass through this additional lens, further refraction occurs. By using a convex or concave lens, the convergence or divergence of light rays can be adjusted, thereby optimizing optical output characteristics: the converging effect can improve the brightness of the emitted light and the sharpness of the pattern center, making the central positioning mark clearer, and providing the ability to adjust the viewing distance; the diverging effect can expand the observation range of the visible pattern, allowing users to observe brilliant dispersion effects over a wider angle range. This enhances the adaptability of the component and the observation experience, allowing flexible selection according to different application scenarios (such as precision positioning or wide field of view display) to achieve better optical performance.

[0035] As attached Figure 3 To be continued Figure 4 As shown, in one embodiment of the present invention, a prism 300 is provided at the first light inlet 101 of the dispersant 100;

[0036] Specifically, after the incident light is refracted by the prism 300, it enters the dispersive element 100 through the first light inlet 101. Its function is that the prism 300 can utilize its refractive properties to more effectively guide and converge the incident light within a wider angular range to the first light inlet 101, increasing the luminous flux entering the component. Furthermore, the prism 300 can pre-disperselate the composite white light, causing it to undergo preliminary spectral separation before entering the dispersive element 100. The light after this pre-modulation undergoes multiple reflections within the dispersive element 100, further enhancing the dispersion effect. Ultimately, this results in richer colors and higher brightness in the emitted light, improving the overall optical efficiency and visual performance of the component.

[0037] The prism 300 is fixed to the front end of the first light inlet 101 by optical bonding or structural clamping, and its material is optical glass or transparent resin.

[0038] In one embodiment of this utility model, the marking is an observation pattern formed by a scratch, print, coating or physical attachment applied to the 200-circumference side of the object of attention through machining, laser etching, printing, coating or material adhesion processes.

[0039] Specifically, the markers, through the difference in refractive index between their material and the transparent body, light absorption characteristics, or induced fluorescence effects, interact with the light propagating inside, creating local contrasts in brightness, color, or luminance in the emitted light field, thus allowing for clear observation by the human eye. When light propagating through multiple reflections / refractions inside the attention object 200 illuminates these markers, optical effects such as scattering, absorption, or secondary emission at the marker interface create local contrasts in brightness, color, or luminance in the original uniform light field, thus modulating and carrying clear pattern information. Finally, these modulated rays, along with the dispersive light, are emitted from the second light outlet 202 and, after being received by the human eye, appear as a visible image with a specific shape, pattern, or color structure. This enhances the sense of layering and artistry of the overall visual effect of "dispersive attention," and more importantly, provides users with stable and clear criteria for distance and center position. By observing changes in the symmetry, magnification, or clarity of the pattern, users can more intuitively and accurately perform distance and positioning, significantly improving the functionality of the component and the human-computer interaction experience.

[0040] The pattern can be distributed regularly or irregularly on one or more sides, and its material can be selected to form a difference in refractive index or absorption / reflection characteristics with the transparent body, such as a metal coating, colored ink or fluorescent material.

[0041] As attached Figure 2 and attached Figure 5 As shown, in one embodiment of the present invention, the dispersant 100 is integrally formed from a transparent material (such as K9 glass or PMMA) or is composed of a transparent shell filled with a transparent liquid (the transparent liquid is filled with reflective micro-fragments that can reflect different spectra or colors).

[0042] Specifically, after the incident white light enters through the first light inlet 101, it is refracted at the interface between the transparent medium and the air. Light of different wavelengths is separated due to the dispersion effect and is reflected multiple times in the cavity under the action of the reflective film on the inner wall, so that the spectrum is fully expanded and temporarily stored. Some of the light energy is finally emitted directionally from the first light outlet 102. This achieves efficient dispersion of incident light and utilization of light energy, providing the component with a dispersive light source with rich colors and uniform brightness.

[0043] As attached Figure 2 and attached Figure 6 As shown, in one embodiment of this utility model, the eyepiece 200 is made of a transparent material (such as K9 glass or PMMA) and is integrally molded or consists of a transparent shell filled with a transparent liquid;

[0044] Specifically, the dispersed light from the dispersive element 100 enters through the second light inlet 201, undergoes multiple refractions and reflections within the transparent medium, and carries pattern information after being marked and modulated. Finally, it exits from the second light outlet 202 at a certain divergence angle, making the emitted light spot present a clear pattern. Users can achieve intuitive and accurate visual positioning and distance judgment by observing the symmetry and visual changes of the pattern, while obtaining a dazzling visual effect.

[0045] Among them, the side of the eye-catching body 200 has a three- or multi-faceted structure.

[0046] In one embodiment of this utility model, the reflective coating layer deposited on the outer surface of the dispersant 100 can be a metal aluminum film or a dielectric distributed Bragg mirror (DBR) with a reflectivity greater than 90%.

[0047] The dispersive attention-generating component provided in this application has dual functions of center positioning and visual ranging. "Dispersion" refers to the component's ability to decompose and diffuse incident visible light in space and spectrum, creating a multi-colored dispersed optical effect. "Attention" refers to both the directional injection of the decomposed light into the human eye, forming a clear visual signal, and the component's ability to effectively attract the user's attention through its dazzling and varied dispersive light spots, thereby enhancing the psychological effect of visual guidance and the user experience.

[0048] This application achieves a compact spatial layout by using an optical path coupling method that connects the first light outlet 102 of the dispersive element 100 with the second light inlet 201 of the spectral object 200. The dispersive element 100 is equivalent to a miniature "spectral generator and memory". Except for the first light inlet 101 and the first light outlet 102, it is fully covered with a high-reflection film, which causes the incident light to be reflected multiple times in the cavity, greatly enhancing the dispersion and temporarily storing the light energy. Then, it is coupled into the spectral object 200 through the first light outlet 102, thereby realizing the miniaturization of the optical path and the integration of functions in the physical structure. Passive positioning and ranging are achieved by using markers. By setting markers on the side of the spectral object 200 to modulate the light field, a group of virtual and real images distributed along the optical axis is formed. The user can achieve precise alignment of the pupil with the optical axis by identifying the farthest and most stable central virtual and real image, thus achieving positioning. At the same time, based on the regular change of the radial position of the outermost virtual and real image with the actual distance, visual distance measurement is achieved after calibration.

[0049] As attached Figure 1 , Figure 2 , Figure 5 To be continued Figure 8 As shown, this utility model also provides a method for using a dispersive attention component, applicable to the aforementioned dispersive attention component, comprising the following steps:

[0050] Includes the following steps:

[0051] S1. Guide the incident light to the first light inlet 101 of the dispersive body 100;

[0052] S2. After multiple refractions and / or reflections within the dispersive body 100, part of the incident light rays exit through the first light ray outlet 102.

[0053] S3. The light emitted from the first light outlet 102 enters the focus 200 through the second light inlet 201, and after refraction and / or reflection within the focus 200, it is finally emitted from the second light outlet 202.

[0054] S4. Position the human eye's pupil within the observation optical path of the second light outlet 202. When the human eye observes through the second light outlet 202, the marker, after refraction by the gaze body 200, forms a group of virtual and real images distributed from near to far along the optical axis (the virtual and real images, whether symmetrically or asymmetrically distributed, together constitute the virtual and real image group. There is a somewhat ambiguous intermediate deviation value between the virtual image group and the real image; this deviation value can be used as a reference position, which serves as the spatial reference center of the image group, effectively improving the accuracy and stability of distance measurement).

[0055] When the human eye pupil observes that the center of the virtual and real image group forms a stable farthest focal point, it is confirmed that the observation point is in the center positioning reference position relative to the object of attention 200. At different observation distances, the visible radial position of the outermost virtual and real image in the virtual and real image group is recorded, and the distance is determined based on the correspondence between the radial position and the observation distance.

[0056] There is an inherent and repeatable correspondence between the radial position of the outermost virtual and real image in the virtual and real image group and the observation distance. This correspondence is determined by the side geometry of the object of attention 200 and the distribution of the markers. Users can achieve visual distance determination by pre-learning or calibration.

[0057] Using the above-mentioned visual positioning and distance determination methods, users can adjust their pupil position to the center positioning position defined by the dispersive focusing body component, and provide an accurate spatial reference point for the subsequent operation of the equipment.

[0058] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
