Description

Technical Field

[0001] This application relates to the field of optical imaging technology, and in particular to a microsphere lens microscopic imaging device and its working method adapted to a mobile phone camera. Background Technology

[0002] Optical microscopy, with its advantages of real-time observation and low optical damage, is widely used in chip defect detection and biological imaging. However, traditional optical microscopy instruments are highly dependent on laboratory environments and stable platforms, and suffer from drawbacks such as large size, complex operation, and poor adaptability to different scenarios, making it difficult to meet the needs of rapid on-site detection. With the leap in imaging performance of smartphones, microscopy systems based on mobile phone platforms have become an important breakthrough direction, showing significant advantages in portability, low cost, and real-time on-site detection.

[0003] While existing mobile phone microscopy solutions improve portability, the focal length is difficult to adjust, and they cannot be compatible with the lens design differences between different brands of mobile phones (such as lens module thickness differences of 1-2mm and varying lens spatial distribution positions). Current solutions generally involve attaching an optical magnifying lens group in front of the main camera of the mobile phone through a clamping device, but such lenses are limited by the diffraction limit of traditional lenses, and the resolution is usually >1μm; moreover, because the lens is fixed, it is difficult to adjust the field of view.

[0004] Furthermore, microsphere lens imaging requires strict alignment with the optical axis. Existing mobile phone microstructures are generally connected to the mobile phone via clamping. During clamping, it is difficult for the lens plane of the mobile phone to be parallel to the plane of the glass slide, resulting in lens focusing inaccuracy. Existing technologies cannot guarantee precise positioning, thus affecting accuracy. Therefore, a microsphere lens microscopic imaging device adapted to mobile phone cameras is proposed to solve the above problems. Summary of the Invention

[0028] Optical microscopy, with its advantages of real-time observation and low optical damage, is widely used in chip defect detection and biological imaging. However, traditional optical microscopy instruments are highly dependent on laboratory environments and stable platforms, and suffer from drawbacks such as large size, complex operation, and poor adaptability to different scenarios, making it difficult to meet the needs of rapid on-site detection. With the leap in imaging performance of smartphones, microscopy systems based on mobile phone platforms have become an important breakthrough direction, showing significant advantages in portability, low cost, and real-time on-site detection.

[0029] While existing mobile phone microscopy solutions improve portability, the focal length is difficult to adjust, and they cannot be compatible with the lens design differences between different brands of mobile phones (such as lens module thickness differences of 1-2mm and varying lens spatial distribution positions). Current solutions generally involve attaching an optical magnifying lens group in front of the main camera of the mobile phone through a clamping device, but such lenses are limited by the diffraction limit of traditional lenses, and the resolution is usually >1μm; moreover, because the lens is fixed, it is difficult to adjust the field of view.

[0030] Furthermore, microsphere lens imaging requires strict alignment with the optical axis. Existing mobile phone microstructures are generally connected to the mobile phone via clamping. During clamping, it is difficult for the lens plane of the mobile phone to be parallel to the plane of the glass slide, resulting in lens focusing inaccuracy. Existing technologies cannot guarantee precise positioning, thus affecting accuracy. Therefore, a microsphere lens microscopic imaging device adapted to mobile phone cameras is proposed to solve the above problems.

[0031] In response, this application proposes a microsphere lens microscopic imaging device adapted to mobile phone cameras. It is fixed to the mobile phone by clamping, which is not limited by the model or type of mobile phone, and has versatility and portability. Moreover, based on easy installation, both the sample placement plate and the lens mounting block can be moved along the x-direction to adjust the field of view. The extension distance of the two clamping pieces can be adjusted independently, which facilitates the adjustment of the focal length and the orientation of the mobile phone lens plane. Compared with the prior art, it has higher precision and thus obtains higher imaging quality.

[0032] In addition, this application also proposes a working method for the microsphere lens microscopic imaging device adapted to the above-mentioned mobile phone camera. By adjusting the extension distance of the two clamping plates respectively, not only can the distance between the mobile phone lens and the microsphere lens be changed to achieve the change of focal length, but the parallelism between the mobile phone lens plane and the sample placement plate can also be finely adjusted, thereby further improving the imaging quality on the basis of portability.

[0033] Reference Figure 1 The microsphere lens microscopic imaging device adapted to a mobile phone camera in the first aspect embodiment of this application includes a fixing frame 100, a sample placement plate 200, a lens mounting block 300, and a clamping assembly 400. The fixing frame 100 is the main structure of the microsphere lens microscopic imaging device adapted to a mobile phone camera. Both the sample placement plate 200 and the lens mounting block 300 are slidably mounted on the fixing frame 100. The sample placement plate 200 is used to hold the sample to be observed, and the lens mounting block 300 is used to mount the lens. The clamping assembly 400 is connected to the fixing frame 100 and is used to directly contact and clamp the mobile phone, thereby maintaining a fixed relationship between the fixing frame 100 and the mobile phone.

[0034] Specifically, the central part of the mounting bracket 100 is hollowed out to provide observation space. Both the sample placement plate 200 and the lens mounting block 300 are slidably mounted in the hollowed-out portion of the mounting bracket 100 along the x-direction. Notably, a microsphere lens 500, which is spherical, is mounted on the lens mounting block 300. The lens mounting block 300 can be stacked with the sample placement plate 200 along the z-direction, allowing light to pass through the sample placement plate 200 and illuminate the microsphere lens 500 on the lens mounting block 300. After refraction by the microsphere lens 500, the light enters the mobile phone lens, completing the image display on the mobile phone lens.

[0035] There are two clamping assemblies 400, each located at one end of the mounting bracket 100. Each clamping assembly 400 includes a stabilizing block 410, an elastic element 420, and a clamping plate 430. The stabilizing block 410 is slidably connected to the end of the mounting bracket 100. The two ends of the elastic element 420 are connected to the mounting bracket 100 and the stabilizing block 410, respectively, and the elastic element 420 drives the stabilizing block 410 closer to the mounting bracket 100. Thus, from an overall perspective, the two stabilizing blocks 410 located at both ends of the mounting bracket 100 move towards the center under the drive of their respective elastic elements 420, achieving a clamping state for the mobile phone. The clamping plate 430 is slidably connected to the stabilizing block 410 along the z-direction. Therefore, by changing the extension distance of the clamping plate 430, the distance between the mobile phone and the sample placement plate 200 can be adjusted, thereby adjusting the focus point to improve imaging quality. The outer side of the stabilizing block 410 is provided with a scale 411 for displaying the movement distance of the clamping piece 430, so that the extension distance of the clamping piece 430 can be finely adjusted by observing the scale on the scale 411. Both clamping pieces 430 can contact the mobile phone and apply force to clamp the mobile phone.

[0036] It is easy to understand that by adjusting the extension distance of the two clamping pieces 430, the distance between the mobile phone and the sample placement plate 200 and the lens mounting block 300 can be adjusted, thereby adjusting the focal point and setting the focus on the sample to be observed, thus improving image quality. Furthermore, when the mobile phone clamping shifts, causing the mobile phone lens plane to be non-parallel to the plane of the sample placement plate 200, the angle of the mobile phone lens can be adjusted by differentially adjusting the extension distance of the two clamping pieces 430, thereby making the mobile phone lens plane more parallel to the plane of the sample placement plate 200, which also improves image quality.

[0037] Furthermore, the sample placement plate 200 is a transparent plate, which facilitates the transmission of light and avoids obstructing the observation process.

[0038] Furthermore, referring to Figure 2 The clamping assembly 400 further includes a first guide post 440. In some embodiments, the first guide post 440 is fixedly connected to the stabilizing block 410, and the clamping piece 430 is slidably connected to the first guide post 440; or, the first guide post 440 is fixedly connected to the clamping piece 430, and the stabilizing block 410 is slidably connected to the first guide post 440. Regardless of the embodiment, the clamping piece 430 is slidably connected to the stabilizing block 410 along the z-direction via the first guide post 440, and the first guide post 440 limits the direction of movement of the clamping piece 430.

[0039] Furthermore, the clamping assembly 400 also includes a screw 450, which is rotatably connected to the stabilizing block 410. The clamping plate 430 has a threaded hole that is threadedly connected to the screw 450. Rotating the screw 450 can drive the clamping plate 430 to move in the z-direction. By using the rotation of the screw 450 to pull the clamping plate 430 to move, the adjustment accuracy of the extension distance of the clamping plate 430 can be improved. Moreover, this screw mechanism has a self-locking function, which can reduce the risk of the clamping plate 430 moving arbitrarily.

[0040] Furthermore, the end of the screw 450 is provided with a nut that is easy to grip, and the side of the nut is provided with multiple grooves to increase the friction with the user's fingers, making it easier for the user to screw the screw 450.

[0041] Furthermore, the clamping piece 430 includes a main body portion 431 extending along the z-direction and an extension portion 432 extending along the x-direction. The main body portion 431 and the extension portion 432 together form an "L"-shaped structure. The extension portion 432 can apply a force in the z-direction to the mobile phone to support it, enhance the stability of the mobile phone after clamping it, and prevent it from falling off the mobile phone.

[0042] Furthermore, both the main body 431 and the extension 432 have a layer of anti-slip rubber 433 applied to the surfaces that can contact the mobile phone to increase the friction with the mobile phone.

[0043] Furthermore, the clamping assembly 400 also includes a second guide post 460. In some embodiments, the second guide post 460 is fixedly connected to the fixing frame 100, and the stabilizing block 410 is slidably connected to the second guide post 460; or, the second guide post 460 is fixedly connected to the stabilizing block 410, and the fixing frame 100 is slidably connected to the second guide post 460. Regardless of the embodiment, the stabilizing block 410 and the fixing frame 100 are slidably connected in the x-direction via the second guide post 460, and the second guide post 460 defines the direction of movement of the stabilizing block 410.

[0044] Specifically, the elastic element 420 is a spring, which is sleeved on the outside of the second guide post 460.

[0045] Furthermore, the mounting bracket 100 has a first groove 110 and a second groove 120 extending in the x-direction in its hollowed-out portion. The sample placement plate 200 is slidably connected to the first groove 110, and the lens mounting block 300 is slidably connected to the second groove 120.

[0046] Furthermore, referring to Figure 3The lens mounting block 300 has a mounting hole in the middle for mounting the microsphere lens 500. The wall of the mounting hole is provided with a fixing rubber ring 310. When the microsphere lens 500 is installed in the mounting hole, the fixing rubber ring 310 can fill the gap between the microsphere lens 500 and the mounting hole, thereby making the installation of the microsphere lens 500 more stable and reducing the risk of loosening.

[0047] A working method according to a second aspect embodiment of this application, which is applied to the aforementioned microsphere lens microscopic imaging device adapted to a mobile phone camera, includes the following steps: S100. Pull the two clamping components 400 apart to make enough space for the phone to enter; S200. Place the mobile phone between the two clamping components 400, release the clamping components 400, and the two clamping pieces 430 respectively abut against the opposite sides of the mobile phone to clamp and fix the mobile phone. S300. Place the sample 600 to be observed on the sample placement plate 200, and move the sample placement plate 200 in front of the mobile phone camera; S400. Move the lens mounting block 300 with the microsphere lens 500 installed in front of the mobile phone camera so that the sample to be observed 600, the microsphere lens 500 and the mobile phone camera are in the same straight line. S500. Based on the markings on the scale 411 on the stabilizer block 410, adjust the extension distance of the two clamping plates 430, adjust the distance between the mobile phone camera and the microsphere lens 500, and adjust the parallelism between the mobile phone lens plane and the sample placement plate 200.
