Abstract Using a highly stable and excellently performed three-component photorefractive (PR) polymer composite, poly(N-vinylcarbazo1e):l -n- butoxyl-2,5-dimethy1-4(4'-nitrophenylazo) benzene:2,4,7-trinitro-9-fluorenone, optical image storage was demonstrated. The dark storage time was 5-7h. The PR response time was measured to be about 200ms at an intensity of 1W/cm2 with an applied electric field of 84 V/μm. A proof-of-principle experiment on real-time correction of distorted images based on phase conjugattion of four-wave mixing geometry was also carried out.
