[0032] like Figure 1 and Figure 2 As shown, a visual bright field microscopic imaging device of a light source array in an embodiment of the present application includes:

[0033] The stage assembly includes a stage 22, the top of which is used to place a cubic object to be imaged;

[0034] A light source assembly, the light source assembly includes an annular light source 4 and a light leak plate 5, the annular light source 4 is arranged on a first light leak hole of the light leak plate 5, the light leak plate 5 is located directly above the loading platform 22 and has a set height from the object to be imaged on the loading platform 22; the number of the first light leak holes is set to four and they are respectively arranged relative to the four sides of the object to be imaged;

[0035] Light source reflection components, four of which are respectively disposed between the light leakage plate 5 and the object to be imaged on the loading platform 22; each light source reflection component comprises a light source reflection box (a first light source reflection box 9, a second light source reflection box 11, a third light source reflection box 14, a fourth light source reflection box 15) having a reflection surface, each reflection surface having a first preset angle and a second preset angle relative to the corresponding first light leakage hole and the side of the object to be imaged, so that the light emitted by the annular light source 4 is sequentially reflected through each first light leakage hole and the corresponding reflection surface to the corresponding side of the object to be imaged;

[0036] The camera assembly includes a camera 2 and a microscope lens 3. The camera 2, the microscope lens 3 and the annular light source 4 are coaxially arranged and connected in sequence along the vertical direction. The camera 2 is used to image each side of the object to be imaged.

[0037] First, the loading platform 22 is firmly mounted on the base of the loading platform assembly, ensuring that its levelness and flatness meet the requirements so that the cubic object to be imaged can be stably placed. The cubic object to be imaged is placed at a designated position on the top of the loading platform 22, ensuring that the object is placed stably and that all four sides are fully exposed to the imaging light path.

[0038] The light leak plate 5 is precisely positioned above the object loading platform 22, and the set height between the light leak plate 5 and the object to be imaged on the loading platform 22 is determined by a measuring tool, for example, the set height is 10 cm. Four first light leak holes are processed on the light leak plate 5, and the positions of the four holes are arranged relative to the four sides of the object to be imaged, respectively, to ensure accurate correspondence in subsequent optical path transmission.

[0039] Carefully install the ring light source 4 on the four first light leakage holes of the light leakage plate 5 to ensure that the light source is firmly installed and emits light evenly. Perform a power-on test on the ring light source 4 to check whether its brightness, color temperature and other parameters meet the imaging requirements, and make corresponding adjustments if necessary.

[0040] When the annular light source 4 is turned on, the light emitted by the light source will be emitted through the four first light leakage holes. After being reflected by the corresponding reflection surfaces, the light is projected onto the four corresponding sides of the object to be imaged according to a predetermined light path, forming uniform illumination.

[0041] Four light source reflection boxes are constructed as light source reflection components. A reflection surface is set inside each light source reflection box, and each reflection surface has a specific first preset angle (such as 45 degrees) and a second preset angle (such as 45 degrees) relative to the corresponding first light leakage hole and the side of the object to be imaged through a precise angle adjustment device. The four light source reflection components are accurately placed between the light leakage plate 5 and the object to be imaged on the loading platform 22 to ensure the accuracy and stability of the light path.

[0042] Connect the camera 2, the microscope lens 3 and the ring light source 4 coaxially in the vertical direction. Install the microscope lens 3 on the lens interface of the camera 2 to ensure that the connection is tight and not loose. Initialize the parameters of the camera 2, including resolution, frame rate, exposure time, etc., and make preliminary optimization adjustments according to the characteristics of the object to be imaged and the imaging requirements. Through the nodal circle thread adjustment of the microscope lens 3 and the knob adjustment of the vertical adjustment mechanism 1, the microscopic defocus algorithm is used to continuously collect data in the interval of the predetermined object distance to solve the optimal focal plane, so as to achieve better imaging quality and surface defect characteristics of micro components.

[0043] With the assistance of the microscope lens 3, the camera 2 begins to perform imaging operations on each side of the illuminated object to be imaged. Since the camera 2, the microscope lens 3 and the ring light source 4 are coaxially arranged, the clarity and accuracy of the imaging can be guaranteed. The camera 2 continuously captures multiple frames of images at a preset frame rate to capture detailed information on the side of the object to be imaged.

[0044] During the imaging process, the parameters of the camera 2 are adjusted in real time according to the imaging effect, such as fine-tuning the exposure time to adapt to different light intensities and the reflective characteristics of the object surface, adjusting the focal length to ensure that the entire side can be clearly imaged, etc. At the same time, the brightness of the ring light source 4 can also be dynamically adjusted to obtain the best imaging contrast.

[0045] After the imaging is completed, the image data captured by the camera 2 is transmitted to a computer or other image processing device for subsequent analysis, processing and storage. Professional image processing software can be used to perform operations such as denoising, contrast enhancement, and edge extraction on the image to better observe and study the microstructure and characteristics of the object to be imaged.

[0046] For example, when imaging a biological cell culture sample (cube shape), the visual bright field microscopic imaging device can clearly obtain information such as the cell's morphology, distribution, and relationship with the surrounding environment on different sides. When inspecting a tiny mechanical part (cube shape), the surface roughness, processing marks, and possible defects on each side of the part can be accurately observed, providing a strong basis for product quality control.

[0047] Through the unique design of the annular light source 4, the light leak plate 5 and four carefully arranged light source reflection components, the four sides of the cubic object to be imaged can be uniformly illuminated and imaged at the same time, achieving the requirements of multi-faceted imaging integrity. This all-round imaging capability greatly enriches the information that can be obtained, avoids the cumbersome process of multiple adjustments of traditional imaging devices or the use of multiple devices for separate imaging, and significantly improves imaging efficiency and data integrity. It is especially suitable for application scenarios with high requirements for overall feature analysis of objects, such as complex crystal structure research or microscopic identification of polyhedral cultural relics.

[0048] Precise light path control and improved imaging quality, the reflective surface of each light source reflection component and the corresponding first light leakage hole and the side of the object to be imaged are set with precise first preset angles and second preset angles. This design ensures that the light emitted by the ring light source 4 can be efficiently and accurately reflected to the corresponding side of the object to be imaged, reducing the scattering and loss of light, thereby improving the uniformity and stability of the illumination. In terms of imaging, stable and uniform illumination helps the camera 2 to obtain clearer and higher-contrast images, effectively improving the imaging quality, which is of great significance for the resolution and detail capture of microscopic structures. For example, in biological cell imaging, the distribution and morphological changes of organelles in cells can be more clearly observed, and tiny circuit defects can be accurately identified in semiconductor chip detection.

[0049] The stage assembly, light source assembly, light source reflection assembly and camera assembly are cleverly combined in an imaging device system, and each assembly is coaxially arranged in the vertical direction and has a reasonable and compact layout. This integrated design not only reduces the footprint of the entire device, making it easier to place and operate in a laboratory or production line, but also reduces the impact of external interference factors such as vibration and dust on the imaging effect that may be introduced due to complex optical path connections, improves the stability and reliability of the device, and is conducive to long-term, high-precision imaging work. For example, in the continuous inspection of tiny parts on industrial production lines, it can ensure the consistency and accuracy of the inspection results.

[0050] The parameters of the device can be flexibly adjusted according to the characteristics of different objects to be imaged. For example, by changing the brightness and color temperature of the ring light source 4 and the exposure time and resolution of the camera 2, it can meet various needs, from imaging transparent or translucent samples in the biomedical field to imaging high-reflectivity metal or ceramic samples in the field of materials science. At the same time, its imaging capability of cubic objects can be easily extended to the imaging applications of other similar polyhedral objects, providing a universal and efficient microscopic imaging solution for research, detection and production processes in multiple disciplines, such as the analysis of mineral crystals in geology, the quality control of new electronic components in the electronics manufacturing industry, and the exploration of the microstructure of ancient cultural relics in archaeology. It has broad application prospects.

A second light leak hole having the same shape and size as the first light leak hole is correspondingly provided on the light source support frame 206, so as to ensure that the light source support frame 206 supports the camera assembly while preventing the light source support frame 206 from blocking the transmission of the annular light source 4.
