Image Storage and Real-Time Distorted Image Correction by Using Photorefractivity in a Stable Photorefractive Polymer Composite

摘要

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