WiMi Hologram Cloud Inc. (NASDAQ: WIMI) ("WiMi" or the "Company"),
a leading global Hologram Augmented Reality ("AR") Technology
provider, today announced that it developed an efficient hologram
calculation using the wavefront recording plane method, which
combines the principles of light wave interference and diffraction.
The method determines the effective visible region by analyzing the
diffraction characteristics of an object point on a
three-dimensional object, and based on this, identifies the
effective hologram size of the object point, thus realizing the
rapid generation of holograms.
WiMi's hologram calculation method using the
wavefront recording plane method mainly consists of four key steps,
each of which is optimized for the hologram generation process to
improve the calculation speed and image quality. Its implementation
requires the integrated use of mathematical models, optical theory,
and computer algorithms.
Sub-hologram generation: According to the
Fresnel diffraction theory, for each point of the 3D object, the
corresponding diffraction field is calculated based on its spatial
coordinates and wavelength. This can be accelerated by numerical
computational methods such as Fast Fourier Transform (FFT).
Optimal segmentation: After obtaining the
preliminary results of the sub-holograms, an optimization algorithm
is used to optimally segment each sub-hologram according to the
distribution of the object points and the diffraction
characteristics to ensure maximum diffraction efficiency and image
clarity.
Accurate diffraction calculation at the
wavefront recording plane (WRP): Using accurate numerical
calculation methods, such as the finite difference method (FDTD) or
other accurate numerical simulation methods, the accurate
diffraction results from the object point to the WRP are
calculated, and the diffraction information from different points
are superimposed to obtain the total complex amplitude information
on the WRP.
Diffracted light field calculation: Based on the
total complex amplitude information on the WRP, the diffraction
theory and optical propagation equation are utilized to calculate
the diffracted light field distribution from the WRP to the
holographic plane, and the final hologram is obtained accordingly.
This step requires the use of optical calculations and numerical
simulation methods to accurately calculate the propagation and
diffraction of the light field.
At the same time, the method utilizes deep
learning technology to improve the accuracy and efficiency of the
algorithm by learning and training on a large amount of hologram
data, which further accelerates the calculation speed of the
hologram. In addition, in practice, hardware devices need to be
optimized, combining high-performance computing platforms and
customized optical components to improve the computational
efficiency and display quality.
WiMi's hologram calculation method using the
wavefront recording plane method is of great significance and
far-reaching value as a new holographic display technology. The
method realizes the rapid generation of holograms by combining the
principle of wavefront precision diffraction and an efficient
calculation algorithm. It breaks through many challenges faced by
the traditional holographic display technology, such as narrow
field of view, serious speckle noise, and slow computation speed,
and brings an important breakthrough for the development of
holographic display technology. The method achieves high efficiency
and versatility in the hologram calculation process by optimizing
the algorithm and pre-calculated components. This makes the
holographic display technology more widely applicable in practical
applications and provides users with a more convenient and fast
holographic display experience.
Through accurate wavefront diffraction
calculation and light field propagation simulation, this method can
realize higher-quality hologram generation and present more
realistic and lifelike holograms for users. This will bring broader
development space for the application scenarios of holographic
display technology, such as providing a better visual experience in
the fields of education, medical care, entertainment, and so
on.
WiMi's hologram calculation method using the
wavefront recording plane method is expected to bring more new
possibilities and opportunities for the holographic display
technology industry. It is not only an important breakthrough in
the field of holographic display technology, but also an important
exploration of the future development direction of holographic
display technology, WiMi will continue to explore and innovate and
is committed to promoting the further development of holographic
display technology, providing users with smarter and more
convenient holographic display solutions, and better holographic
display experience, and helping holographic display technology to
be widely used and developed around the world.
