Abstract: Holographic method of recording and reconstructing a wavefront, from an array of light spots on a dark field, to propagate the reconstructed wavefront so as to illuminate the light spots to the exclusion of the dark field.

Abstract: A birefringence polarizer divides incident light into two emergent, mutually perpendicularly polarized beams. The incident light is linearly polarized, its azimuth of polarization being rotatable by a rotatable half-wave retardation plate. A similar plate in the path of one of the emergent beams controls its azimuth of polarization. The emergent light beams are thus controllable as to relative intensity and directions of polarization.
