Abstract: A coaxial bi-modal imaging system is produced by aligning a microwave transceiver, an optical camera and an antenna array in a coaxial configuration. The microwave transceiver is operable to emit microwave radiation to illuminate an object and to receive reflected microwave radiation reflected from the object to capture a microwave image of the object. The antenna array includes a plurality of antenna elements, each programmable with a respective transmit direction coefficient to direct the microwave radiation emitted from said microwave transceiver toward a target on the object, and each programmable with a respective receive direction coefficient to direct the reflected microwave radiation reflected from said target towards said microwave transceiver. The optical camera is configured to capture an optical image of said object.

Abstract: The invention provides a microanalytical device for analyzing a fluid sample containing at least one analyte molecule. The device is constructed from a substrate and a cover plate each having a substantially planar surface and a microchannel formed therein. The cover plate is placed over the substrate such that the cover plate microchannel is arranged in opposing relationship with the substrate microchannel. A membrane is interposed between the substrate and the cover and has at least one pore sized to allow passage of the analyte molecule from the substrate microchannel to the cover plate microchannel. An analyte altering moiety is attached to an interior surface of the pore and is capable of chemically altering the analyte molecule. Also disclosed are a method for chemically altering and transporting an analyte molecule in a fluid and a method for identifying a plurality of biomolecules.

Abstract: A detection signal that quantifies a resonant interaction between a quantum absorber and incident electro-magnetic radiation is generated. The quantum absorber is irradiated with the incident electro-magnetic radiation. The quantum absorber absorbs a portion of the incident electro-magnetic radiation and generates fluorescent electro-magnetic radiation in response to it. The quantum absorber additionally transmits the unabsorbed portion of the incident electro-magnetic radiation. The unabsorbed portion of the incident electro-magnetic radiation is detected to generate a first signal that has a first signal-to-noise ratio. The fluorescent electro-magnetic radiation is detected to generate a second signal that has a second signal-to-noise ratio. The first signal and the second signal are combined to generate the detection signal. The detection signal has a signal-to-noise ratio greater than the first signal-to-noise ratio and the second signal-to-noise ratio.

Abstract: An optical collimating assembly for imaging light from a display. The optical assembly includes first and second linear polarization filters having polarization directions that are orthogonal to one another. A folded imaging assembly that includes a first beam splitter, a first ¼ wave plate, and a second beam splitter is located between the polarization filters. A second ¼ wave plate is also located between the polarization filters. The first ¼ wave plate has a birefringence axis that is orthogonal to the birefringence axis of the second ¼ wave plate. In the preferred embodiment of the present invention, the ¼ wave plates are constructed from the same birefringent material. One of the reflectors is preferably constructed from a material having a reflectivity that depends on the direction of linear polarization of light striking the beam splitter.
