    Abstract: 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.

  • Patent number: 9183771
    Abstract: A projector configured to provide higher resolution output without increasing pixel resolution in a light modulator is disclosed. The projector may introduce an optical element between a light modulator and an imaging lens. The optical element may provide pixel sharing of a target image. The pixel sharing may be produced by, for example, making smaller copies of pixels. Selected copies of pixels may be passed to the imaging lens to display an output image with selected areas of higher density pixels.
