The maturation of nanotechnology has led to the rapid development of microtechnology, MEMS (Micro-Electronic-Mechanical systems) technology, which has contributed significantly to the miniaturization of medical devices. This has led to the creation of medical optoelectronic micro-sensors. WiMi Hologram Cloud, Inc. (NASDAQ:WIMI) is an AR-based holographic service and product provider. Focused on providing innovative interactive holographic AR experiences for its customers, WiMi develops a CPLD (Complex Programmable Logic Device) endoscopy system based on hologram acquisition technology.
WiMi’s CPLD wireless endoscopic system is based on a micro-electro-mechanical system. The system consists of various micro-sensors for sensing external digital information such as force, heat, and light, control actuators, signal processing, and communication interfaces, as well as control circuits and power supplies. The system integrates the acquisition, processing, and actuation of holographic digital information in a multifunctional microsystem.
The system consists of a host computer and a hologram acquisition endoscope. The hologram acquisition endoscope collects the original image. After compression and transmission, the compressed hologram digital image is transmitted to the host through wireless communication, the host receives the compressed data and sends it to the host system, and the host hologram restoration management software displays the hologram digital image.
The hologram acquisition endoscope is designed with a CPLD chip and has a high-precision CMOS lens for hologram acquisition and a data and address bus. It enables holographic lossless digital image compression and wireless data transmission, including purchasing and controlling system data such as pressure, temperature, and light sensing.
WiMi’s endoscopy system enables the continuous acquisition of holographic data and temperature, pressure, humidity, and light sensing control. The addition of holographic image data is the core of the system. The host control system sends commands, and the system management software sends the orders to the hologram acquisition endoscope via wireless signals. The CPLD writes the collected holographic data into multiple parallel memories and compresses them through the controller to improve the system’s holographic high-precision image transmission efficiency. The host management software sends instructions to receive the lossless compressed digital content, decodes the compressed digital images, and displays the 3D holographic endoscopic graphics.
The high volume and relevance of data from hologram acquisition technology require redundant lossless data compression. The high image quality requirements in the medical field necessitate the use of lossless compression algorithms. Through WiMi’s holographic digital content compression and processing system, coding redundancy, spatial redundancy, temporal redundancy, and uncorrelated information are removed to solve the coding redundancy caused by the word code in digital content being larger than the optimal coding to form entropy, spatial redundancy caused by correlation between adjacent pixels in digital content, temporal redundancy caused by the existence of a correlation between different frames in the digital content sequence, different color or spectrum brought redundancy caused by correlation between other structures in a sequence of digital content, spectral redundancy caused by different colors or ranges, etc., to optimize data results. This allows us to increase transmission speed and performance time significantly. Then lossless restoration is performed to provide a high-fidelity repair of the endoscopic hologram data. The addition of various sensor data allows doctors to have a more intuitive and comprehensive understanding of the patient’s profile, improving their judgment of the disease and giving a proper treatment plan.
