[0032] As shown in Figure 1 and Figure 2 The visual bright field microscopic imaging device of the light source array of the embodiment of the present application comprises:

[0033] A stage assembly, the stage assembly comprises a loading platform 22, the top of the loading platform 22 is used to place a cuboid-shaped object to be imaged;

[0034] A light source assembly, the light source assembly comprises a ring-shaped light source 4 and a light leakage plate 5, the ring-shaped light source 4 is arranged on the first light leakage hole of the light leakage plate 5, the light leakage 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 leakage hole is four and is arranged with respect to four side surfaces of the object to be imaged respectively;

[0035] A light source reflection assembly, the light source reflection assembly is arranged four and is located between the light leakage plate 5 and the object to be imaged on the loading platform 22; each light source reflection assembly comprises a light source reflection box body (first light source reflection box body 9, second light source reflection box body 11, third light source reflection box body 14, fourth light source reflection box body 15) with a reflection surface, each reflection surface has a first preset angle and a second preset angle with respect to the corresponding first light leakage hole and the side surface of the object to be imaged respectively, so that the light emitted by the ring-shaped light source 4 is reflected to the corresponding side surface of the object to be imaged in turn through each first light leakage hole and the corresponding reflection surface;

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

[0037] First, the loading platform 22 is firmly installed on the base of the stage assembly, and the levelness and flatness thereof are ensured to meet the requirements, so that the cuboid-shaped object to be imaged can be stably placed. The cuboid-shaped object to be imaged is placed on the top of the loading platform 22 at a designated position, and it is ensured that the object is placed stably and the four side surfaces can be fully exposed in the imaging light path range.

[0038] The light leakage plate 5 is accurately positioned above the object platform 22, and the set height between the light leakage plate 5 and the object to be imaged on the object platform 22 is determined by measuring tools, for example, the set height is 10 cm. Four first light leakage holes are machined on the light leakage plate 5, and the positions of the four holes are respectively arranged relative to the four side surfaces of the object to be imaged, so as to accurately correspond in the subsequent light path transmission.

[0039] The annular light source 4 is carefully installed on the four first light leakage holes of the light leakage plate 5, and the light source is ensured to be stably installed and uniformly emit light. The annular light source 4 is tested for power-on, and the brightness, color temperature and other parameters are checked to see if they meet the imaging requirements. If necessary, corresponding adjustments can be made.

[0040] The annular light source 4 is turned on, and the light emitted by the light source is emitted through the four first light leakage holes. After being reflected by the corresponding reflecting surface, the light is projected onto the four corresponding side surfaces of the object to be imaged according to the predetermined light path, forming uniform illumination.

[0041] Four light source reflection boxes are respectively constructed as light source reflection assemblies. The reflecting surface is arranged inside each light source reflection box, and through the precise angle adjusting device, each reflecting 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 surface of the object to be imaged. The four light source reflection assemblies are accurately placed between the light leakage plate 5 and the object to be imaged on the object platform 22, so as to ensure the accuracy and stability of the light path.

[0042] The camera 2, the microscope lens 3 and the annular light source 4 are coaxially connected in sequence along the vertical direction. The microscope lens 3 is installed on the lens interface of the camera 2, and the connection is ensured to be tight and without looseness. The camera 2 is initialized and set, including resolution, frame rate, exposure time, etc., and preliminary optimization and adjustment are made according to the characteristics of the object to be imaged and the imaging requirements. Through the adjustment of the ring thread of the microscope lens 3 and the knob adjustment of the vertical adjustment mechanism 1, and combined with the microscopic defocusing algorithm, the best focal plane is solved in the interval of the predetermined object distance to achieve better imaging quality and surface defect characteristics of the micro component.

[0043] The camera 2 starts the imaging operation of each side surface of the illuminated object to be imaged with the assistance of the microscope lens 3. Since the camera 2, the microscope lens 3 and the annular light source 4 are coaxially arranged, the clarity and accuracy of the imaging can be ensured. The camera 2 continuously shoots multiple frames of images according to the preset frame rate to capture the detailed information of the side surface 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 object surface reflection characteristics, adjusting the focal length to ensure that the entire side is clearly imaged, etc. At the same time, the brightness of the ring-shaped light source 4 can also be dynamically adjusted to obtain the best imaging contrast.

[0045] After imaging is completed, the image data obtained 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, edge extraction, etc. on the image, in order to better observe and study the microstructure and features of the object to be imaged.

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

[0047] Through the unique design of the ring-shaped light source 4, the light leakage plate 5 and the four carefully laid out light source reflection assemblies, uniform illumination and imaging of the four sides of the cubic object to be imaged can be achieved simultaneously, meeting the requirements of multi-surface imaging integrity. This all-around imaging capability greatly enriches the information that can be obtained, avoids the tedious process of adjusting or using multiple devices for imaging in traditional imaging devices, significantly improves the imaging efficiency and data integrity, and is especially suitable for application scenarios that require high overall feature analysis of the object, such as complex crystal structure research or microscopic identification of polyhedral cultural relics, etc.

[0048] Precise light path control and imaging quality improvement, the reflecting surface of each light source reflection assembly, the corresponding first light leakage hole and the side of the object to be imaged are provided with precise first and second preset angles. This design ensures that the light emitted by the ring-shaped light source 4 can be efficiently and accurately reflected onto the corresponding side of the object to be imaged, reducing light scattering and loss, thereby improving the uniformity and stability of the light. In terms of imaging, stable and uniform light helps the camera 2 to obtain clearer and higher-contrast images, effectively improving the imaging quality, which is of great significance for microstructure resolution and detail capture, such as more clearly observing the distribution and morphological changes of organelles in cells in biological cell imaging, and accurately identifying small circuit defects in semiconductor chip detection.

[0049] The object table assembly, the light source assembly, the light source reflection assembly and the camera assembly are ingeniously combined in an imaging device system, and each assembly is coaxially arranged in a vertical direction and has a reasonable and compact layout. Such integrated design not only reduces the floor area of the entire device, facilitates installation and operation on a laboratory or production line, but also reduces external interference factors that may be introduced due to complex connection of the light path, such as vibration, dust and the like, thereby improving the stability and reliability of the device, and facilitating long-time and high-precision imaging work, for example, in the continuous detection task of micro parts on an industrial production line, the consistency and accuracy of the detection results can be ensured.

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