    摘要: Transmission efficiency and/or spatial resolution provided by resonant apertures can be enhanced by disposing a tip on part of the screen that extends laterally into the aperture. For example, a tip disposed on the ridge of a C-shaped aperture can dramatically improve performance. A spatial resolution of λ/50 has been experimentally demonstrated with this approach. The combination of high spatial resolution and high transmission efficiency provided by this approach enables many applications, such as near field optical probes for near field scanning optical microscopy (NSOM). Another application is high resolution electron sources, where an photoelectron emitter can be disposed at or near a tip+aperture structure such that the high resolution optical near-field provides a correspondingly high resolution electron source.

    摘要: A low cost and lightweight interchangeable lens system is provided. The lens system includes two aspheric elements that is usable both for page-based and bit-based data storage systems. The lens system has a large field of view up to ±50 degrees and a high numerical aperture up to 0.8. The invention reduces cost and weight of the objective lenses and is usable with the servoing technology. The invention provides a long working distance of 20% of the focal length and provides sufficient physical space to accommodate media and aberration corrections, which enable a media interchangeable and compatible system among the both optical recording formats.

    摘要: An improved surface plasmon resonance (SPR) sensor is provided based on direct measurement of the Goos-Hänchen effect. Sensor sensitivity is enhanced by selecting the thickness of the metallic layer of the SPR sensor to be close to a critical thickness dcr where the effect of the surface plasmon resonance on the Goos-Hänchen shift is most pronounced. Overall sensor sensitivity is surprisingly found to improve with this approach, even though the measurement is based on a second order effect (i.e., the Goos-Hänchen shift) instead of the first order reflectance change measured in conventional SPR sensor approaches. The invention is also applicable to sensors based on measurements of other non-specular reflection parameters, such as temporal shifts, frequency shifts, and/or angular shifts.

    摘要: Digital data bits are stored at storage locations at plural depths within a holographic storage medium as selective, localized alterations in a format hologram. Micro-localized regions of a reflection format hologram extending throughout the medium are deleted by focusing a high-power laser beam at desired storage locations. The deletion regions have a lower reflectivity than the surrounding parts of the format hologram. Tunable-focus storage and retrieval heads, as well as dynamic aberration compensators, are used for multi-depth access. Storage and retrieval may each be achieved with a single head.

    摘要: Partially overlapping holograms are stored in a cylindrical volume holographic storage medium capable of rotation about and translation along its longitudinal axis. The reference and signal beams are mutually perpendicular, and each is perpendicular to the longitudinal axis. An index-matched housing encloses the medium laterally. An optional helically-varying optical axis (c-axis) orientation allows recording at constant angular intervals over a full revolution. Signals from stored pages are used to dynamically adjust the positioning of the medium relative to the light beams as the medium continuously spins at high velocity, and to control the access of the signal beam to the readout camera.

    摘要: A method for promoting enhanced nondestructive reconstruction of holograms recorded in photorefractive media involves control of the polarization states of the reconstruction beam and the recording beams, control of the cummulative recording energy, and use of a relatively high external field applied across the media during recording which is subsequently reduced during reconstruction. The resulting reconstruction history characteristics are selectively tailored by adjusting the polarization and intensity of the reconstruction beam, the recording geometry, and the applied voltage during reconstruction and recording, and various other parameters. In general, the reconstruction efficiency starts at a relatively high level, initially reduces, and then subsequently grows above the starting value, and can be made substantially nondestructive over a typical reconstruction cycle, with erasure times exceeding forty-five minutes.
