Description

TECHNICAL FIELD

[0001] The present application relates to the optical device technology, specifically to a dispersion attention body assembly and a method thereof. BACKGROUND

[0002] In the current field of optical equipment and visual aid technology, especially in the applications such as industrial alignment, medical positioning, virtual reality interaction, etc. which require high-precision visual positioning and real-time distance judgment, the demand for highly integrated and miniaturized optical assemblies is increasingly urgent. Such assemblies need to achieve two core functions in extremely limited space: one is to provide a clear and stable visual center reference to assist users in completing pupil self-positioning; the other is to achieve rapid distance judgment through optical feedback without external device calibration.

[0003] The traditional optical implementation method often adopts a "kaleidoscope" structure based on multi-mirror reflection, which can generate symmetrical and visually stunning patterns through three-mirror reflection, and has a certain visual attraction. However, such structures are generally large in size and complex in optical path, making it difficult to integrate into modern compact devices. At the same time, most of the existing technologies have single functions and cannot integrate multiple functions such as dispersion enhancement, visual guidance, center positioning, and distance measurement in the same miniature optical structure, thereby limiting the application effect in visual aid scenes that require high visual attraction, fast response, and intuitive interpretation. SUMMARY

[0004] The purpose of the present application is to provide a dispersion attention body assembly and a method thereof to solve the problems of bulky size, single function, and low integration in the existing visual positioning devices, and to realize the integrated application of visual attraction and accurate optical guidance in miniaturized devices.

[0005] To achieve the above purpose, the present application provides a dispersion attention body assembly, which comprises:

[0006] A dispersion body made of transparent material, the dispersion body is provided with a first light inlet and a first light outlet, the first light inlet is used for the incident light to enter the dispersion body, and the outer surface of the dispersion body is coated with a reflective coating layer except for the first light inlet and the first light outlet;

[0007] An attention body made of transparent material, the attention body is provided with a second light inlet and a second light outlet, and the outer surface of the attention body 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 attention body is a multi-faceted structure, and at least one of the facets is provided with a mark for observation.

[0010] Another aspect of the present application provides a method for using a dispersion attention body assembly, which is suitable for the dispersion attention body assembly described above, and comprises the following steps:

[0011] S1, directing the incident light to the first light entrance of the dispersion body;

[0012] S2, after multiple refraction and / or reflection in the dispersion body, part of the light is emitted through the first light exit;

[0013] S3, the light emitted from the first light exit enters the attention body through the second light entrance, and after refraction and / or reflection in the attention body, it is finally emitted by the second light exit;

[0014] S4, the pupil of the human eye is located in the observation light path of the second light exit 202, and when the pupil of the human eye observes the second light exit 202, the mark forms a virtual and real image group distributed from near to far along the optical axis direction after refraction in the attention body 200 (the virtual image and the real image symmetrically or asymmetrically distributed together form a virtual and real image group. There is an ambiguous intermediate deviation value between the virtual image group and the real image. The deviation value at a certain position can be used as a reference position, which is the spatial reference center of the image group, which can effectively improve the accuracy and stability of distance measurement);

[0015] When the center of the virtual and real image group is observed to form a stable farthest focal point, it is confirmed that the observation point at this time is located at the center positioning reference position relative to the attention body 200. Under 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 corresponding relationship between the radial position and the observation distance.

[0016] Compared with the prior art, the dispersion attention body assembly and the method for using the same provided by the present application can efficiently realize dispersion, spectrum temporary storage, multi-path modulation and directional emission of incident light through the dispersion body and the attention body, not only significantly enhancing the visual attraction and color richness of the emitted light, but also enabling the observer to obtain a stable and clear center positioning reference and intuitive and accurate visual distance feedback, effectively solving the problem that the visual guidance, positioning and distance measurement functions are difficult to be considered in the limited space in the prior art.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] As attached Figure 1 To be continued Figure 8 As shown, the present invention provides a dispersive attention component, comprising:

[0031] 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.

[0032] 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.

[0033] The second light inlet 201 receives the light emitted from the first light outlet 102.

[0034] The peripheral surface of the attention body 200 is a multi-faceted structure, and at least one of the facets is provided with a mark (not shown in the figure) for observation.

[0035] Specifically, after the incident light enters the dispersion body 100 through the first light inlet 101, the light is reflected and refracted multiple times inside the dispersion body 100 due to the reflective coating on the outer surface of the dispersion body 100. The white light is decomposed into a multi-color spectrum and temporarily stored in the dispersion body 100. Part of the light is emitted through the first light outlet 102 and enters the second light inlet 201 of the attention body 200. Similarly, the outer surface of the attention body 200 is coated with a reflective coating. After further reflection and refraction in the attention body 200, the light is finally emitted through the second light outlet 202 at a certain divergence angle. When the observer receives the emitted light through the pupil, he can see the symmetrical pattern or stripes formed by the mark. The central pattern corresponds to the farthest observation distance, and the outer pattern corresponds to the closer distance, thereby realizing the functions of visual positioning and distance measurement. At the same time, due to the superposition of dispersion effect and multi-faceted reflection, the emitted light presents a colorful visual effect, significantly enhancing the visual appeal and psychological attention.

[0036] The first light outlet 102 of the dispersion body 100 and the second light inlet 201 of the attention body 200 are mutually connected by optical cementing, mechanical clamping, or threaded connection, etc. to ensure the continuity of the light path and reduce the loss of light energy at the interface.

[0037] As shown in FIG. 2, the dispersion body 100 is a multi-faceted structure, and the first light inlet 101 and the first light outlet 102 are arranged on the same facet. Figure 7 As shown in FIG. 3, the attention body 200 is a multi-faceted structure, and the second light inlet 201 and the second light outlet 202 are arranged on the same facet. Figure 8As shown, the shape of the second light ray outlet 202 can be designed according to actual optical requirements, for example, it can be configured as a plane, a concave spherical surface or a convex spherical surface, etc. When it is configured as a concave spherical surface, the structure is equivalent to a concave spherical lens, which can modulate the emission behavior of the light rays inside the object of interest 200. Specifically, when the light rays from the side of the object of interest 200, which cannot be observed due to exceeding the critical angle, are incident on the concave spherical structure, the light rays are refracted at a large angle under the condition that the medium angle is less than the critical angle of total reflection, the emission direction is adjusted and enters the range that can be received by the human eye, thereby converting the original invisible area to visible, significantly expanding the effective observation area. The propagation path of the light rays can be calculated and designed according to Snell's Law. For example, when the refractive index n1 of the transparent medium used by the object of interest 200 is 1.49, and a certain light ray is incident on the light-emitting surface of the concave spherical surface from the inside of the medium at an incident angle i (the angle with the normal line, for example, 38.05°), the refractive angle r in the air can be calculated according to the refractive index formula n1 x sin(i) = n2 x sin(r), where n2 is the refractive index of air (1.00). Substituting the numerical value, we get:

[0038] sin(r) = (n1 x sin(i)) / n2 = (1.49 x sin(38.05°)) / 1.00 ≈ 0.919, that is, the refractive angle

[0039] r ≈ arcsin(0.919) ≈ 66.69°; after the refracted light ray is emitted at a large angle, its reverse extension line can fall within the pupil receiving range of the human eye, thereby converting the light rays originally in the unobservable area to visible to the user, significantly expanding the effective observation field of view.

[0040] In an embodiment of the present application, a lens (not shown in the figure) is added to the side of the second light ray outlet 202 close to the pupil of the human eye.

[0041] Specifically, the lens can be a convex lens or a concave lens, and is fixed by optical adhesive bonding, mechanical clamping or integral molding with the outlet of the object of interest 200. When the divergent or convergent light rays emitted from the second light ray outlet 202 pass through the additional lens, further refraction occurs. The use of a convex lens or a concave lens can adjust the convergence or divergence of the light rays, thereby optimizing the optical output characteristics: the convergence effect can improve the brightness of the emitted light and the central sharpness of the pattern, making the central positioning mark clearer and having the ability to adjust the near vision distance; the divergence effect can expand the observation range of the visible pattern, so that the user can observe the beautiful dispersion effect in a wider angle range. The adaptability and observation experience of the component are enhanced, allowing flexible selection according to different application scenarios (such as precise positioning or wide field display) to achieve better optical performance.

[0042] As shown in the accompanyingFigure 3 To the attached Figure 4 As shown in the figure, in one embodiment of the present application, a prism 300 is arranged at the first light inlet 101 of the dispersion body 100;

[0043] Specifically, the incident light is refracted by the prism 300 and then enters the interior of the dispersion body 100 from the first light inlet 101. The prism 300 can use its refractive properties to more effectively guide and converge the incident light in a larger angle range to the first light inlet 101, thereby increasing the light flux entering the assembly. The prism 300 can also produce pre-dispersion on the composite white light, so that the light is preliminarily spectrally separated before entering the dispersion body 100. The light after the pre-modulation is reflected multiple times in the dispersion body 100, and the dispersion effect is further enhanced. Finally, the emitted light is richer in color and higher in brightness, and the overall optical efficiency and visual performance of the assembly are improved.

[0044] The prism 300 is fixed to the front end of the first light inlet 101 by optical cementing or structural clamping, and is made of optical glass or transparent resin.

[0045] In one embodiment of the present application, the observation pattern is formed by marks, prints, plating layers or physical attachments arranged on the side surface of the attention body 200 by mechanical processing, laser etching, printing, plating or material attachment processes.

[0046] Specifically, the marks form local contrasts in brightness, color or brightness in the emitted light field when interacting with the internally propagating light due to the refractive index difference between the material and the transparent main body, light absorption characteristics or induced fluorescence effect, so that they can be clearly observed by the human eye. When the light propagating multiple times / refracting in the interior of the attention body 200 irradiates these marks, local contrasts in brightness, color or brightness are formed in the original uniform light field due to scattering, absorption or secondary emission at the mark interface, so that the pattern information is clearly modulated and carried. Finally, these modulated light and dispersed light are emitted from the second light outlet 202, and the visible image with specific shape, pattern or color structure is presented in the vision after being received by the human eye. This enhances the level and artistry of the overall visual effect of the "dispersion attention", and more importantly, provides the user with stable and clear distance and center position criteria. By observing the symmetry, magnification or clarity of the pattern, the user can more intuitively and accurately complete visual distance measurement and positioning, significantly improving the functionality and human-computer interaction experience of the assembly.

[0047] The pattern can be regularly or irregularly distributed on one or more side surfaces, and the material can be selected to have a refractive index difference or absorption / reflection characteristic difference with the transparent main body, such as a metal plating layer, colored ink or fluorescent material.

[0048] As shown in the accompanying Figure 2 and the accompanying Figure 5 In an embodiment of the present application, the dispersion body 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.

[0049] Specifically, after the incident white light enters through the first light inlet 101, refraction occurs at the interface between the transparent medium and the air, different wavelengths of light are separated due to the dispersion effect, and multiple reflections occur in the cavity under the action of the inner wall reflective film, so that the spectrum is fully expanded and temporarily stored, and part of the light energy is finally emitted from the first light outlet 102. The high-efficiency dispersion and light energy utilization of the incident light are realized, and a dispersion light source with rich colors and uniform brightness is provided for the assembly.

[0050] As shown in the accompanying Figure 2 and the accompanying Figure 6 In an embodiment of the present application, the dispersion body 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.

[0052] In an embodiment of the present application, the dispersion body 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.

[0053] In an embodiment of the present application, the reflective film layer coated on the outer surface of the dispersion body 100 can use aluminum film or dielectric distributed Bragg reflector (DBR), and the reflectivity is greater than 90%.

[0054] The dispersion focusing body assembly provided by the present application has the dual functions of center positioning and visual distance measurement. The "dispersion" refers to the dispersion focusing body assembly capable of decomposing and diffusing the incident visible light in space and spectrum to form a multi-color dispersed optical effect. The "focusing" refers to the fact that part of the decomposed light is finally injected into the human eye to form a clear visual signal, and the dispersion focusing body assembly effectively attracts the attention of the user through the colorful and varied dispersion light spot, thereby enhancing the psychological effect of visual guidance and user experience.

[0055] The present application realizes compact space layout by using the light path coupling mode that the first light ray exit 102 of the disperser 100 is connected with the second light ray entrance 201 of the object 200, the disperser 100 is equivalent to a micro “spectrum generator and memory”, the high reflection film is covered comprehensively except the first light ray entrance 101 and the first light ray exit 102, the incident light is reflected in the cavity for many times, the dispersion is greatly enhanced, the light energy is temporarily stored, and then is coupled into the object 200 through the first light ray exit 102, so that the light path miniaturization and function integration are realized in the physical structure; and the passive positioning and distance measurement are realized by using the mark; the mark modulation light field is arranged on the side of the object 200, the virtual and real image groups distributed along the optical axis are formed; the user completes the accurate alignment of the pupil and the optical axis by identifying the farthest and stable central virtual and real image, and realizes the positioning; and the visual distance measurement is realized according to the regular change of the radial position of the outermost virtual and real image with the actual distance.

[0056] Embodiment two

[0057] As shown in the accompanying drawings Figure 1 , Figure 2 , Figure 5 to the accompanying drawings Figure 8 , the present application also provides a use method of the dispersing object assembly, which is suitable for the dispersing object assembly provided in embodiment one, and comprises the following steps:

[0060] S2, after the incident light is refracted and / or reflected in the disperser 100 for many times, part of the light is emitted through the first light ray exit 102;

[0061] S3, the light emitted from the first light ray exit 102 enters the object 200 through the second light ray entrance 201, and is finally emitted from the second light ray exit 202 after being refracted and / or reflected in the object 200;

[0062] S4, the pupil of the human eye is located in the observation light path of the second light ray exit 202, when the pupil of the human eye observes from the second light ray exit 202, the mark forms the virtual and real image groups distributed from near to far along the optical axis direction after being refracted in the object 200 (the virtual image and the real image symmetrically or asymmetrically distributed together form the virtual and real image groups. There is an intermediate deviation value between the virtual image group and the real image group, the deviation value at a certain position can be used as a reference position, the position is used as the spatial reference center of the image group, and the accuracy and stability of distance measurement can be effectively improved);

[0064] There is an inherent and repeatable corresponding relationship between the radial position of the outermost virtual-real image in the virtual-real image group and the observation distance, which is determined by the side geometry and the distribution of the markers of the object 200. The user can achieve visual distance measurement by pre-learning or calibration;

[0065] Through the above-mentioned visual positioning and distance measurement method, the user can adjust the pupil position to the center positioning position defined by the dispersion object assembly, and provide an accurate spatial reference point for the subsequent operation of the device.
