| With the development of technology,the demand of information has increased,the efficient storage materials are demanded also.Most of researchers like the phenathrenequinon doped poly methyl methacry(PQ/PMMA) because of high diffraction efficiency,high resolution,high senstitivty and so on.At present,most of studies conside to PQ/PMMA polymer material sanple were conducted by continuous light,this paper study on the basis of previous studies,studing PQ/PMMA polymer material sanple by puls light.Firstly,the preparation of PQ/PMMA process improvement and optimization were studied.The material sample’s sensitivity is improved by increasing photosensitizer,Increasing reaction temperature can improve the response speed of materials. At the same time, the material sample’s absorption spectrum is measured, with the absorption coefficient of materials of different wavelengths of light is studied also. Study on the optical properties of the sample material.PQ/PMMA’s optical properties is studied on plus exposure, grating formation process and dark diffusion enhancement effect on single pulse and multi pulse exposure are studied.This paper analysis of the dark diffusion enhancement phenomenon.Secondly, the dynamicformingprocess on short time exposureholographic grating are studied. The material sample photo induce polymerization process and diffusion process on short exposure time are analyzed. Finally,effects of incident angle, frequency and other factors on the performance of a single grating. The single grating is improved.This paper studied the holographic storage characteristics of puls posure material sample also, loading image information and complete reproduction on puls posure,in thispaper hasprovedthefeasibility ofoptical pulse loadingimageinformation.Provides sup port for the further study of pulsed light load dynamic image information. Finally, this paper analysis of the factors of errors in the experiment, and gives the scheme ofreducing the experimental error. |
