| Abstract | ||
| In this research the holographic sensitive film has been fabrication by photopolymers ,such as PVAand acryl amide in addition to the triethanol amina and toluidine blue, using He-Ne lsser of wave length 632.8 nm and its powers of 50 mWatt.the diffraction grating of 1000 line/mm ang diffraction efficincy of 80% have been obtained. After that the effect of an exposure time has been studing on the diffraction efficiency, and the besttime for exposing was 4 minutes. | ||
