| Abstract: | An optical holographic associative memory utilizing a self- pumped phase conjugator and a thin piece of Ce:Fe:LiNbO3 crystal as feedback device of thresholdingand memory medium respectively is presented in this paper. The "cat" self-pumpedphase-conjugator of 16°-cut Cu: KNSBN shows rapid response and good image qualityand the thin piece of Ce: Fe: LiNbO3 crystal with low absorption coefficient has a widerange of angluar response. The complete image output can be addressed with less than 25% of stored image output can be addressed with less than 25% of stored image. |
