Non-iterative method for batch generation of dynamic holograms

In recent years, computer-generated holograms have found widespread applications in display, storage, and biomedical sectors. However, the generation of holograms typically depends on iterative calculation methods, which lead to compromised calculation speeds and pose challenges in producing high-precision dynamic holograms in bulk. We introduce a non-iterative approach to generating dynamic holograms, which fragments the image into several independent elements via a specific core mapping matrix. This method allows for the translation and rotation of image elements via mapping. Experimental results reveal that the calculation time for generating a single hologram (1000 × 1000) using this method is within 200 ms, representing a more than 10-fold speedup compared to traditional iterative methods. This significant improvement broadens the potential applications of dynamic holography.
