Data and Pixel Match in Holographic Disc Storage
The holographic disc storage (HDS) technology has become one of the potential new types of optical storage technologies. In order to obtain precise input and output information, hence, reduce the bit-error rate in the retrieved data, the accurate pixel matching between the whole high-resolution page of SLM and CCD must be ensured. We discuss the method and technique of pixel matching based on volume holographic storage theory, and then accomplished an optical system to realize pixel match by imaging a random data both mask and SLM of 512×512 pixels. The results showed that 1∶1 pixel matching between spatial light modulator (SLM) and CCD was realized, and a raw bit-error-rate (BER) of 1.5×10-4 (2.5×10-4 of mask) was achieved.
