摘要： A method and a compact apparatus to read shift-multiplexed holograms on a storage medium without the need for any lenses, and without the need for moving the storage medium. The shift-multiplexed holograms have centers at different locations. The apparatus can generate an array of diverging spherical waves of reference beams, each for illuminating one of the holograms. Each hologram is read as an image on a detector array by illuminating that hologram with a corresponding diverging spherical wave of reference beam. Different holograms can be read by illuminating the medium with a different diverging spherical reference beam. The diverging beams can be from an array of sources, or can be from switching one source.

摘要： An optical memory for storing and/or reading data on an optical disk. The optical disk incorporates a material in which holographic gratings can be created, and subsequently detected, at plural locations within the disk by an electro-optical head. Creation and detection of holographic gratings with variable diffraction efficiency is possible with the electro-optical head. Multiple holographic gratings can also be created at each one of the plural locations via a beam of light which has a different wavelength or point of focus. These data elements can be read by the electro-optical head using a beam of light sequentially varied in wavelength or point of focus to correspond to the multiple holographic gratings to be recorded.

摘要： A method and a system to re-align onto a detector array a holographic image of a Fourier region hologram stored in a medium, with the medium spinning around a first axis, and the hologram being generated by a reference beam and a signal beam. In generating the hologram, the reference beam is incident on the medium with respect to a second axis at a second-axis-incident angle, and a third axis at a third-axis-incident angle, such that the holographic image of the hologram when reproduced by the reference beam is aligned onto the detector array. Also, the three axes are substantially orthogonal to each other. As the medium spins, the medium's orientation can change through tilting with respect to the second and the third axes so that the holographic image when reproduced by the reference beam is not aligned onto the detector array. In one embodiment, the holographic image is re-aligned onto the detector array by tilting the reference beam such that when re-aligned, the incident angle of the reference beam on the medium with respect to the second axis is intentionally tilted to be different from the second-axis-incident angle, and with respect to the third axis to be different from the third-axis-incident angle.

摘要： An optical memory for storing and/or reading data on an optical disk. The optical disk incorporates a material in which holographic gratings can be created at plural locations within the disk. An electro-optical head which is capable of creating these holographic gratings at any one of the plural locations is employed. The head is additionally capable of detecting the presence or absence of a holographic grating at any one of these plural locations. The presence of the holographic grating could indicate a first binary state and the absence of the holographic grating indicate a second state. Alternately, the electro-optical head could be used to vary the diffraction efficiency of the holographic gratings during their creation. In that case, the head would also be capable of detecting this variation in efficiency and produce a proportional detection signal. This signal would be used as an indicator of the value of the stored data element. The material of the optical disk is further capable of having multiple holographic gratings created at each one of the plural locations. These multiple holographic gratings are created via a beam of light from the electro-optical head which has a different wavelength or point of focus. In reading these holographic gratings, a beam of light generated by the electro-optical head is sequentially varied in wavelength or point of focus to correspond to the wavelength or point of focus and the sequence of wavelengths or points of focus employed to record each one of the data elements recorded.

摘要： A differential interference contrast (DIC) determination device and method utilizes an illumination source, a layer having a pair of two apertures that receive illumination from the illumination source, and a photodetector to receive Young's interference from the illumination passing through the pair of two apertures. In addition, a surface wave assisted optofluidic microscope and method utilize an illumination source, a fluid channel having a layer with at least one aperture as a surface, and a photodetector that receives a signal based on the illumination passing through the aperture. The layer is corrugated (e.g., via fabrication) and parameters of the corrugation optimize the signal received on the photodetector.

摘要： In the present invention, a volume holographic optical element is used as a pump coupler. The holographic coupler allows at least one pump wavelength to be coupled into the laser medium. The direction of the pump beam onto the coupler is not co-linear with the direction of the signal beam out of the coupler. The invention further provides the coupling of more than one pump wavelengths using a single holographic coupler element while maintaining the high isolation between pump and signal beam. The invention further provides a narrow-band reflection grating of various efficiencies for the signal beam (as part of the laser cavity).

摘要： A method of microfluidic control via localized heating includes providing a microchannel structure with a base region that is partially filled with a volume of liquid being separated from a gas by a liquid-gas interface region. The base region includes one or more physical structures. The method further includes supplying energy input to a portion of the one or more physical structures within the volume of liquid in a vicinity of the liquid-gas interface region to cause localized heating of the portion of the one or more physical structures. The method also includes transferring heat from the portion of the one or more physical structures to surrounding liquid in the vicinity of the liquid-gas interface region and generating an interphase mass transport at the liquid-gas interface region or across a gas bubble while the volume of liquid and the gas remain to be substantially at ambient temperature.
