    摘要： A detector includes a voltage source for providing a bias voltage and first and second non-insulating layers, which are spaced apart such that the bias voltage can be applied therebetween and form an antenna for receiving electromagnetic radiation and directing it to a specific location within the detector. The detector also includes an arrangement serving as a transport of electrons, including tunneling, between and to the first and second non-insulating layers when electromagnetic radiation is received at the antenna. The arrangement includes a first insulating layer and a second layer configured such that using only the first insulating in the arrangement would result in a given value of nonlinearity in the transport of electrons while the inclusion of the second layer increases the nonlinearity above the given value. A portion of the electromagnetic radiation incident on the antenna is converted to an electrical signal at an output.

    摘要： An optical system for providing an in-focus, extended depth of field image on a projection surface includes an encoded mask or light encoder for preceding the light to include object information (or, equivalently, information about the desired image), and an extended depth of field (EDF) mask, for extending the depth of field of the projection system. In addition to including object information, the encoded mask encodes the light from the light source to account for the variations introduced by the EDF mask in extending the depth of field, so that no post processing is required.

    摘要： This invention provides achromatic liquid crystal compound retarders, achromatic polarization switches, and achromatic shutters using the liquid crystal compound retarders. It further provides achromatic variable retardance smectic liquid crystal retarders. The compound retarder of this invention comprises a central liquid crystal retarder unit and two external passive retarders positioned in series with and on either side of the liquid crystal retarder unit. The liquid crystal retarder unit comprises either (1) a rotatable smectic liquid crystal half-wave retarder or (2) first and second liquid crystal variable retarders having retardance switchable between zero and half-wave. The external passive retarders are equal in retardance and orientation to each other. Design equations determine the retardance of the external elements and their orientation relative to the central retarder to obtain a particular achromatic retardance for the compound structure.
