Digital holography (DH) has attracted the attention of scientists and engineers since it came out. It uses the photoelectric sensor to replace the traditional holographic dry plate to realize the digital recording of the hologram, and then carries on the light diffraction simulation with the help of the computer algorithm, thus realizes the three-dimensional reconstruction of the object. The advantages of this technology are simple operation, low cost, high imaging efficiency and can provide three-dimensional structure information of objects. However, due to the large amount of digital hologram data, the computational complexity of the reconstruction algorithm increases accordingly, which poses a great challenge to real-time applications.

It is reported that aiming at the computing bottleneck faced by digital holography (DH) technology under the condition of high resolution, NASDAQ:WIMI has proposed an innovative solution OpenHoloFusion: digital holography fusion reconstruction technology based on open computing language. As a representative of heterogeneous computing, OpenCL integrates a variety of computing devices, such as central processing unit (CPU) and graphics processing unit (GPU), and provides powerful parallel computing capabilities. In this technology, aiming at the digital holographic convolution reconstruction algorithm, it gives full play to the heterogeneous collaborative computing ability of OpenCL, works together with CPU and GPU, and accelerates the execution of the reconstruction algorithm through the data parallel mode.

The data show that WIMI micro-American holography accelerates the convolution reconstruction algorithm of digital holography by using open computing language (OpenCL) and OpenHoloFusion technology, which brings great impetus to the practical application of digital holography. This innovation is regarded as an important milestone in the field of digital holography and is expected to bring about revolutionary changes in the fields of microscopic technology, three-dimensional imaging, biological imaging and so on.

WIMI micro-holographic OpenHoloFusion: the implementation steps of digital holographic fusion reconstruction technology based on open computing language, from algorithm optimization to parallel computing, and then to OpenCL programming and data processing, each step is an important step to achieve a technological breakthrough.

Algorithm optimization and parallelization: firstly, OpenHoloFusion digital holographic convolution reconstruction algorithm is optimized. The calculation process of the algorithm is divided into several independent steps, which can be processed in parallel. This optimization divides the whole reconstruction process into smaller tasks, so that each task can be executed in parallel on different computing units, thus improving the overall computational efficiency.

OpenCL programming: based on the optimized algorithm, the OpenCL programming model is used to realize the parallel computing of the algorithm on different computing devices. OpenCL provides a unified programming interface for heterogeneous computing, so that the same set of code can run on many different types of computing devices. With OpenCL, you can split the code into different kernels (Kernel) that run on CPU and GPU respectively.

Data parallel mode: in order to make better use of parallel computing, OpenHoloFusion technology adopts data parallel mode. This involves dividing the digital hologram data to be processed into a plurality of small blocks, each of which is assigned to a different computing device. In this way, each computing device can process its own data blocks independently, thus realizing efficient parallel computing.

Collaborative computing and data synchronization: in the actual implementation phase, collaborative computing and data synchronization are needed between CPU and GPU. CPU is responsible for coordinating the whole calculation process, dividing the data and sending it to GPU for processing. At the same time, GPU returns the processed data to CPU to complete the final step of holographic reconstruction. This kind of collaborative computing and data synchronization ensures the correctness and consistency of the whole process.

In addition, Weimei holography (NASDAQ:WIMI) has conducted extensive testing and optimization of OpenHoloFusion technology. Experiments are carried out on digital holograms with different resolutions and on a variety of GPU platforms, and a large number of performance data are collected. Through the analysis of these data, the effect of the acceleration scheme can be determined and targeted optimization can be made to further improve the performance. By comparing the performance difference between the acceleration scheme and the traditional method, the effectiveness of "OpenHoloFusion" technology is verified. The significant improvement in the execution efficiency of the accelerated digital holographic reconstruction algorithm proves the breakthrough and practicability of this technology.

The implementation logic of WIMI micro-holographic OpenHoloFusion digital holographic fusion reconstruction technology based on open computing language involves many key steps, such as algorithm optimization, OpenCL programming, data parallel processing, collaborative computing, testing and verification, etc. The organic combination of these steps enables the technology to make efficient use of computing resources, accelerate and optimize the reconstruction of digital holography, and bring more efficient and accurate data processing capabilities to various application fields.

As a high-quality imaging technology, digital holography has a wide range of applications. However, because of its high computational complexity, the traditional serial computing method is inefficient. WIMI micro-American holographic OpenHoloFusion technology works together with CPU and GPU through the heterogeneous computing power of OpenCL, which significantly improves the computational efficiency of digital holographic reconstruction, so that digital holography can be applied to the actual scene more quickly. At the same time, the wide application of digital holography is restricted by real-time requirements. Traditional methods can not meet the needs of real-time processing, and the acceleration ability of "OpenHoloFusion" technology provides the possibility for real-time applications, such as image diagnosis, industrial detection and other fields, real-time processing is very important for fast decision-making.

Accelerated digital holography can not only be applied in traditional fields such as microscopy and imaging, but also can be extended to virtual reality, augmented reality, cultural heritage protection and other fields. This will lead to more possibilities and promote development and innovation in these areas. This technology can provide higher quality 3D imaging data and is of great significance in areas where accurate 3D information is needed, such as product design, biological research and cultural heritage protection. This will contribute to in-depth research and more accurate decision-making.

It can be said that the digital holographic fusion and reconstruction technology based on open computing language of WIMI micro-beauty holography not only has important value in the field of digital holography, but also has a far-reaching impact on many industries and fields. Its acceleration ability will promote the wide application of digital holography and bring more efficient and accurate data processing capabilities, thus promoting the development of scientific research, industrial applications and cultural heritage.
