    • Abstract
  • A method based on parallel processing of field programmable gate array(FPGA)technology was put forward to accelerate the computation speed of computer-generated hologram(CGH).Its Fresnel CGH of a point and two-dimension images were produced particularly and the numerical reconstruction of CGH was realized.The experimental results show that the computational speed of a resolution of 50×50 hologram based on FPGA is 165-fold of traditional MATLAB implementation.The study is helpful for implementing real-time CGH.
