Abstract: The present invention relates to a method and apparatus for performing two dimension fast fourier transform for hologram processing. A method for processing a hologram according to an embodiment of the present disclosure may comprise: generating complex data by multiplying the digital image by a random phase value; performing inverse fast fourier transform (IFFT) processing on the complex data; generating pattern information by multiplying a result of the IFFT processing by a quadrant phase; and processing the hologram based on the pattern information. Here, the IFFT processing may comprise a IFFT core operation that performs row-base IFFT and column-base IFFT on the complex data, and a single shift IFFT operation that applies a predefined rule to a result of one or more of the row-based IFFT or the column-based IFFT.
