Devices based on surface plasmon filters having at least one metal-dielectric interface to support surface plasmon waves. A multi-layer-coupled surface plasmon notch filter is provided to have more than two symmetric metal-dielectric interfaces coupled with one another to produce a transmission spectral window with desired spectral profile and bandwidth. Such notch filters can form various color filtering devices for color flat panel displays.

A miniature, ultra-high resolution, and color scanning microscope using microchannel and solid-state technology that does not require focus adjustment. One embodiment includes a source of collimated radiant energy for illuminating a sample, a plurality of narrow angle filters comprising a microchannel structure to permit the passage of only unscattered radiant energy through the microchannels with some portion of the radiant energy entering the microchannels from the sample, a solid-state sensor array attached to the microchannel structure, the microchannels being aligned with an element of the solid-state sensor array, that portion of the radiant energy entering the microchannels parallel to the microchannel walls travels to the sensor element generating an electrical signal from which an image is reconstructed by an external device, and a moving element for movement of the microchannel structure relative to the sample. Discloses a method for scanning samples whereby the sensor array elements trace parallel paths that are arbitrarily close to the parallel paths traced by other elements of the sensor array.

The present disclosure includes an image processing technique that is capable to increase spatial resolution of single frame images beyond diffraction limit. If an image is taken by diffraction limited optical system with regularly spaced pixel detectors, and if the spacing of pixels of the detectors is much small than the diffraction pattern, then the spatial resolution of the image can be increased beyond the diffraction limit by using neighboring-pixel-optical-transfer-function (NPOTF) in Fourier Domain with periodical boundary conditions.

In general, this disclosure relates to techniques for transmitting data for applications using one or more available channels of a spectrum. One example method comprises transforming data into a digital broadcast format, identifying at least one available channel of a spectrum, and transmitting the transformed data in the at least one identified available channel.
