    摘要： A super-resolving imaging apparatus employs diffractive optical elements placed on the imaging lens. This element, and the use of a modified Scheimpflug arrangement allow the conversion of degrees of freedom in one axis of a field of view to a larger degree of freedom in another axis in order to obtain a high resolution image with a wide depth of focus and large field of view. Replicas created by the diffractive elements are mutually shifted by subpixel amounts, and are combined using a Gabor transform, which is facilitated by a spatial mask placed over the detector array. The apparatus is suitable for performing distance estimation on an object within the field of view.

    摘要： A method for encoding zero-order phase-only holograms, and the holograms so encoded. The amplitude and phase of each point of a discrete mathematical transform, such as a Fourier transform, of an image to be encoded, are encoded as regions of a corresponding pixel of a transparent filter, with suitably selected fractional areas and optical path lengths. The various optical path lengths may be created by manipulating the filter's index of refraction, or by manipulating the thickness of the filter, preferably by etching. Various encoding schemes are presented, appropriate to etching systems with low lateral resolution, to etching systems with high lateral resolution but depth resolution limited to a discrete number of depths, and to etching systems with limited resolution both laterally and in depth.

    摘要： This application describes an optical switching method for selectively directing an input beam to at least one of two output channels. The input beam impinges on a polarizing beam splitting surface, splitting the input beam into two beam components of different polarizations propagating along different optical paths. These beam components then pass through a controllable polarization rotating medium which selectively affects the polarization of each of the beam components. The beam components are then directed back onto the polarizing beam splitting surface again, producing at least one output beam which propagates toward at least one selected output channel, depending on the state of the medium. The polarizing beam splitting surface is fabricated on a block of the controllable polarization rotating medium, and the input beam also passes through the medium before being split into two beam components by the polarizing beam splitting surface.
