This paper presents a compression algorithm applicable for transmitting a HPO hologram data. The proposed algorithm exploits a modulating function to compress the bandwidth of an object wave, resulting in data reduction due to relaxed Nyquist sampling constraints. At the receiver, the compressed data will be interpolated and compensated via being divided by the modulating function. We derive the algorithm and present compression rate. Finally, we show the validity of the proposed algorithm by simulation where a reconstructed image from undersampled data is compared with a reconstructed image obtained from proposed algorithm.
