Abstract
We have experimentally evaluated the coherent addition technique, and revealed that the coherent addition can enhance detected data intensity and realize clear three-level data retrieving. Moreover, we have achieved great improvements in the multiplexed performance, which are the SNR gain of +3.5 dB and the data density increase with the factor of 2. We consider that this technique will strongly contribute to future holographic technologies.
