摘要
Abstract
In order to improve the generating speed to the three-dimensional object’s calculation hologram,an improved al-gorithm based on the“host”Fresnel wave zone method is proposed. The two-dimensional“host”Fresnel wave zone is converted to two one-dimensional wave zones according to the diffraction distance,and then the desired Fresnel wave zones are matched with the size of the display device according to the actual application. Finally,the obtained Fresnel wave zones are superim-posed to achieve three-dimensional object’s hologram. Compared to the previous algorithm,the improved algorithm occupies less memory space,its computing speed has been significantly improved and a high quality reconstructed image generated by the DMD can be obtained.关键词
