  • In order to measure the phase modulation characteristics of type LC-R2500,made by Germany HOLOEY company,the relationship between image gray and phase shift was obtained based on double-slit interference.The image encoded by phase retrieval algorithm was input to spatial light modulator,theoretical analysis and experimental research were deployed.Experimental results show the optical reconstructed image is conformal to the numerical reconstructed image,which proves the veracity of measurement of phase modulation characteristics.
