WiMi patents holographic real-time imaging system
A leading Chinese hologram augmented reality company, WiMi Hologram Cloud Inc., has obtained a patent for its holographic real-time imaging system with atomized particle sizes between 2μm to 4μm. The poatent has demonstrated the ongoing progress of WiMi’s independent R&D efforts and enabled WiMi to further refine its IP protection system, fortify its technology leadership, and enhance its core competitiveness.
The imaging system covered by the patent has replaced the traditional dry plates with a spatial light modulator that is capable of achieving real-time optical production through the utilization of computer-generated digital holograms. Compared with traditional optical holography technology, the system has a series of advantages, such as a computer interface, user-friendly operations, and real-time displays.
The real-time imaging system also includes an input module, a carrier module, and a screen module. The input module is based on a computer-generated hologram. The carrier module is comprised of a laser, an expanded beam collimator lens, a polarizer, a spatial light modulator, a deflector, and a Fourier lens. The laser’s beam output passes through these components to project the object in the input module onto the screen module.
The system also creates a hologram database to store experimental and background holographic data. During the data collection process, the holographic real-time imaging system deletes the original data from prior hologram experiments, obtains the droplet atomization data, and conducts grayscale processing for the droplet atomization data. After median filtering, data binarization, and the filling process, the system obtains and calibrates the graphically filled holographic data. The screen module comprises a holographic electrostatic atomizer, which produces atomization particles that are between 2μm and 4μm in size and have atomization volumes between 100ml/h and 150ml/h to form particle curtains that are between 3cm and 20cm in width. In addition, the system has adopted transmissive and electrically addressable spatial light modulation for its spatial light modulator.
The complexity of the non-uniform electric field along with the interconnection between the electric field and the flow field have resulted in increased difficulties throughout the holographic electrostatic atomization crushing process. Consequently, the system utilizes a dual-phase liquid holographic electrostatic atomization device to combine pressure atomization with holographic electrostatic atomization for algorithmic processing. First, the algorithms process the holographic electrostatic atomization and liquid charging mode. After this is completed, the holographic real-time imaging system establishes a mathematical algorithm model for the non-dimensional distribution of atomized droplets. Lastly, the system combines its mathematical algorithm model with another non-dimensional distribution algorithm model to conduct voltage and air measurements.
The patent also covers holographic electrostatic nebulization, which leverages the interactions between the electric field force, Coulomb force, droplet surface tension, and droplet surface stickiness to achieve nebulization. Compared with other atomization methods, holographic electrostatic atomization has the advantages of smaller atomization particle sizes, a singular particle size, and wide spatial dispersion. By controlling the parameters of different algorithms, the system can achieve atomization sizes between 2μm and 4μm for different atomized particles. Holographic electrostatic atomization can now be adopted in a wide variety of areas, including medical, industrial, environmental, transportation, electrostatic imaging, 3D printing, and electric vehicles, as well as in other fields in the future.
