Abstract:
1. An apparatus for compressing holographic data including an image capture device for capturing an image of an interference pattern reconstructed by irradiating a reference beam on a holographic medium and converting the captured image into a series of m-bit data, where m>l, comprising: a splitter for removing least significant j bits from the m-bit data and dividing m−j bits of the m-bit data into most significant k bits and remaining m−j−k bits; a compressor for compressing the most significant k bits into l bits; and a merger for combining the l bits outputted by the compressor and the m−j−k bits outputted by the splitter to output n bits, wherein m, j, k, l and n represent positive integers and l<k and n=l+m−j−k.
