Wireless Endoscopy System Leverages Holographic Imaging for CPLD

A new holographic imaging-based endoscopy system for Complex Programmable Logic Device (CPLD) aims to advance the miniaturization of medical devices and the development of medical optoelectronic microsensors.

WiMi Hologram Cloud, Inc. (Beijing, China) is developing a CPLD wireless endoscopy system that relies on a microelectromechanical system composed of microsensors for detecting external digital information, controlling actuators, signal processing, and communication interfaces, along with control circuits and power supplies. This integrated microsystem facilitates the capture, processing, and execution of holographic digital information, offering multiple functions. The system includes a host and a hologram acquisition endoscope that captures the original image. The image undergoes compressed transmission processing and is wirelessly transmitted to the host, which then forwards the compressed data to the host system for display through hologram restoration management software.

Equipped with a CPLD chip and a high-precision CMOS lens, the hologram acquisition endoscope is designed for hologram capture and data and address bus management. It achieves holographic lossless digital image compression and wireless data transmission, including the acquisition and control of system data such as pressure, temperature, and light sensing. The system allows continuous holographic data collection and control of temperature, pressure, humidity, and light sensing. Hologram data acquisition is the system's core function. The host control system sends commands, and the system management software wirelessly transmits these commands to the hologram acquisition endoscope.

The hologram acquisition endoscope receives the image acquisition command and controls the CPLD to acquire the data. The CPLD writes the collected holographic data images to multiple parallel memories and compresses them through the controller. The parallel processing of data improves the transmission efficiency of holographic high-precision images of the system. 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 data volume and correlation of hologram acquisition imaging technology require redundant lossless data compression. The medical field requires high image quality, so lossless compression algorithms must be used. With WiMi's holographic digital content compression and processing system, coding redundancy, spatial redundancy, temporal redundancy, and irrelevant information can be eliminated.

The system can solve the coding redundancy in digital content where the word code is greater than the entropy of the optimal coding formation; spatial redundancy caused by correlation between adjacent pixels; temporal redundancy caused by the existence of a correlation between different frames in the sequence, spectral redundancy caused by correlation brought by different colors or spectra, etc. The optimized data can significantly improve transmission speed and efficiency. After that, the system performs lossless restoration, which plays a high-fidelity restoration of the endoscopic hologram data. With various types of sensor data, doctors can have a more intuitive and comprehensive understanding of the patient's profile, improve their judgment of the disease, and give proper treatment plans.
