摘要： An optical information recording/reproducing apparatus and method thereof which compensate for the effect of mechanical instability on holographic data storage. A time dependent deviation profile of an optical beam during recording is determined. The time dependent deviation profile is related to a phase profile to be applied to a reference beam during recording or reproduction of a hologram, and the related phase profile is applied to the reference beam during recording or reproduction of the hologram.

摘要： An optical lens and method for designing the lens are disclosed. The lens includes a first surface and a second surface. Light emitted from multiple light emitting elements enters the lens through a central section of the first surface. The light can be reflected from a reflective central section of the second surface and/or undergo total internal reflection at an outer ring section of the second surface one or more times before exiting the lens through the outer ring section of the second surface. Upon exiting the lens, the light beam has a predetermined divergence angle and has a fairly uniform color in the far field even if the multiple light emitting elements have different peak wavelengths.

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： 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 projection type image display apparatus for projecting an image onto a screen includes a light source, a beam shape converter, a beam divider, a beam superimposer, a processing unit, and a projection lens. In operation, the light source emits a light beam. The beam shape converter converts a sectional shape of the light beam into a different shape. For example, the beam shape converter can convert a circular cross section into a rectangular cross section. The beam divider then spatially divides the converted light beam into plural light beams. The beam divider can include, for example, a first prism array that divides the converted light beam horizontally and vertically into four beams. The beam superimposer superimposes the plural light beams onto a target surface, such as a liquid crystal panel. The beam superimposer can include, for example, a second prism array and a beam collimator that superimpose the plural light beams on the target surface. The processing unit supplies a signal so as to display an image on the target surface. The projection lens projects the image onto the screen by the superimposed beam. This apparatus can improve the uniformity of illuminance distribution and the light utilization efficiency, while maintaining high directivity of light.
