The holographic storage of diffraction patterns in a three-dimensional media is described from a vector viewpoint derived from the Kirchhoff diffraction integral. The sensitivity of the reconstruction to wavelength and to the orientation of the readout beam is calculated, and experimental results are given.
A new optical system concept for processing data from synthetic-aperture radars is described. The optical systems are multilens, anamorphic telescopes including spherical and cylindrical lenses. The new method has as its basis two well-known properties of lenses: (a) the longitudinal magnification of an imaging system is equal to the square of the lateral magnification; and (b) a telescope provides an image with magnification independent of the object position.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
