Abstract
An apparatus for compressing holographic data includes an image capture device for capturing an image of an interference pattern reconstructed by irradiating a reference beam and converting the image into m bits. In such an apparatus, a splitter removes least significant j bits from the m-bit data and divides m−j bits of the m-bit data into most significant k bits and remaining m−j−k bits. Thereafter, a compressor converts the most significant k bits into l bits, which is combined with the m−j−k bits to output n bits, wherein l<k and n=l+m−j−k. In this way, by compressing a certain number of most significant bits of the m-bit data and thus relatively increasing the number of the remaining least significant bits of the m-bit data, the BER of final reconstructed image data can be improved.
