摘要： A method and apparatus used for detecting gaseous chemicals. The method and apparatus use an interferometer to filter received light by wavelength, creating an image only using light with wavelengths that are affected by the presence of a gaseous chemical. A reference image composed of light with wavelengths unaffected by the presence of a gaseous chemical is also created and used as a reference. A gaseous chemical is detected where the ratio of the intensity of the two images changes. Despite the high spectral resolution of the filter, the system can operate with a very wide field of view.

摘要： An imaging apparatus and corresponding method according to an embodiment of the present invention enables high-resolution, wide-field-of-view, high sensitivity imaging. An embodiment of the invention is a camera system that utilizes motion of an optical element, such as a spatial filtering mask or of the camera itself, to apply different spatial filtering functions to a scene to be imaged. Features of a spatial filtering mask implementing the different filtering functions are adjacent along an axis of the spatial mask, and a pitch of the features of the mask is smaller than a pitch of the sensor elements. An imaging reconstructor having knowledge of the filtering functions can produce a high-resolution image from corresponding low-resolution coded imaging data captured by the imaging system. This approach offers advantages over conventional high-resolution, wide-field imaging, including an ability to use large-pitch, lower cost sensor arrays, and transfer and store much less data.

摘要： The ability to communicate with a specific subject at a prescribed location who lacks any communications equipment opens up many intriguing possibilities. Communications across noisy rooms, hail and warn applications, and localized communications directed at only the intended recipient are a few possibilities. We disclose and show localized acoustic communications, which we call photoacoustic communications, with a listener at long standoff distances using a modulated laser transmitted toward the receiver's ear. The optically encoded information is converted into acoustic messages via the photoacoustic effect. The photoacoustic conversion of the optical information into an audible signal occurs via the absorption of the light by ambient water vapor in the near area of the receiver's ear followed by airborne acoustic transmission to the ear. The recipient requires no external communications equipment to receive audible messages.

摘要： A wafer-scale satellite bus and a manner of making the same include using wafer reconstruction techniques to stack functional diced circuits onto each other and bond them. The disclosed techniques allow for a variety of functions in each die, including providing, without limitation: ground-based communications, attitude and propulsion control, fuel tanks and thrusters, and power generation. The wafers are initially manufactured according to a common wafer design that provides electrical and power interconnects, then different wafers are further processed using subsystem-specific techniques. The circuits on differently-processed wafers are reconstructed into a single stack using e.g. wafer bonding. Surface components are mounted, and the circuitry is diced to form the final satellites. Mission-specific functions can be incorporated, illustratively by surface-mounting, to the bus at an appropriate stage of assembly, on-wafer circuitry or instrument packages for performing these functions.

摘要： Hyperspectral imaging spectrometers have applications in environmental monitoring, biomedical imaging, surveillance, biological or chemical hazard detection, agriculture, and minerology. Nevertheless, their high cost and complexity has limited the number of fielded spaceborne hyperspectral imagers. To address these challenges, the wide field-of-view (FOV) hyperspectral imaging spectrometers disclosed here use computational imaging techniques to get high performance from smaller, noisier, and less-expensive components (e.g., uncooled microbolometers). They use platform motion and spectrally coded focal-plane masks to temporally modulate the optical spectrum, enabling simultaneous measurement of multiple spectral bins. Demodulation of this coded pattern returns an optical spectrum in each pixel. As a result, these computational reconfigurable imaging spectrometers are more suitable for small space and air platforms with strict size, weight, and power constraints, as well as applications where smaller or less expensive packaging is desired.
