Pattern Recognition with Joint Transform Correlators — Recent Developmentsl Wiener filter has been less utilized due to its more difficult implementation. Nevertheless Wiener filter can be used both for restoration as well as recognition of signals and images, and their use becomes more frequent. An optical implementation using joint transform correlators is presented her

Storage of 3D Information on 2D Elementss only a view of the object from a limited angular window and not the . contained in the object. Moreover, optically recorded holograms, as well as conventional computer generated ones, do not exploit the storage capacity of the medium in an efficient.. This paper describes procedures for optimal st

Generalized Super Resolution Approach Based on the Degrees of Freedom Hyper-Space Adaptationent resolution. We will also distinguish between the space bandwidth (SW) chart of a signal and of a system. The importance of the dynamic range of the detector as an additional factor that determines the number of degrees of freedom will be emphasized. Finally, we introduce the 3-D SW adaptation pr

Planar Diffractive Elements for Compact Opticsation is composed of cascaded gratings recorded on a single substrate. The first grating diffracts the incident light from the source so that it will be trapped inside the substrate by total internal reflection, while the last grating in the cascade diffracts the light out of the substrate to a dete

Design and Fabrication Issues in Subwavelength Diffractive Optical Elementsngth and a depth on the order of the wavelength for operation in the visible or near-infrared region. If nearly periodic rather than strictly periodic elements are considered, this opens the way for a new generation of optical components, where phase is modulated by changing the duty cycle of the gr
