Abstract
Dark reaction is a common phenomenon in holographic recording of photoinduced polymer materials, which has some influence on the recording effect of materials. Now we design an experiment to prepare polymethyl methacrylate materials doped with different phenanthrene quinone (PQ) concentrations, and observe their changes in bit error rate, signal-to-noise ratio and diffraction intensity after dark reaction. The results show that the higher the concentration of PQ doping, the higher the diffraction intensity after dark reaction, but too high concentration will lead to the increase of bit error rate and signal-to-noise ratio decrease. It is proved that the material with 1wt% of PQ doping concentration also has lower bit error rate, higher signal-to-noise ratio and relatively higher diffraction intensity after dark reaction.
