发明名称 COMPUTER GENERATED HOLOGRAM, GENERATION METHOD, AND EXPOSURE APPARATUS
摘要 <p>A computer generated hologram which forms a light intensity distribution on a predetermined plane by giving a phase distribution to a wavefront of incident light, the hologram comprising a plurality of anisotropic cells each including an anisotropic medium configured to change a polarization state of the incident light, and a plurality of isotropic cells each including an isotropic medium configured not to change a polarization state of the incident light, wherein a linearly polarized light component, in a first direction, of the incident light forms a first light intensity distribution on the predetermined plane, and a linearly polarized light component, in a second direction perpendicular to the first direction, of the incident light forms a second light intensity distribution different from the first light intensity distribution on the predetermined plane.</p>
