In this paper, the photo-induced birefringence technique is used to study the optical storage and optical modulation characteristics of two novel azo-based optoelectronic functional materials. The results of the comparative study show that the polymer containing azo side chains has better light storage function, while the azo small molecule doped polymer is more suitable for light modulation. In this paper, the azo small molecule doped polymer films are used to amplify and attenuate the first-order self-diffraction by changing the polarization direction of the additional polarized light, so that the polarization-modulated optical holography technique is completed in the range of 0 ° to 90 °
