Paper Abstract

In digital holographic disc storage, in order to achieve accurate data quickly read and write, and reduce the bit error rate, it is necessary to make pixel 1:1 match between spatial light modulator (SLM) and charge coupled device (CCD). However, how to make the Fourier lens precision assembly and achieve pixel match is a difficult problem. In this paper, based on the Moire fringe of precision measurement technology, a method was to put forward because some Moire fringe appearance can indicate the location error of machine parts and magnification of lens, on the point of angle and cycle analysis of Moire fringe, this problem can be solve. Experiment showed that use of this method the pixel 1:1 match between SLM and CCD achieved. The raw bit error rate of SLM reached 1.5x10-4 and 2.5x10-4 for mask.
