    Abstract: A 3D package for semiconductor thermal management can include a 3D submount forming a mechanical block including at least one embedded channel formed within the mechanical block and configured to accept cooling liquid therethrough, a first tubular connection for providing cooling liquid to the at least one embedded channel, and a second tubular connection for removing cooling liquid from the at least one embedded channel. Integrated slots can be provided for accepting and mounting semiconductor components. Mounting holes can be formed in the mechanical block for securing optical elements. At least one semiconductor laser array die can be secured to the mechanical block at the integrated slots, wherein the at least one semiconductor laser array die is kept cool by the cooling liquid flowing through the at least one embedded channel.

    Abstract: A hyperspectral imaging system has a processor to receive hyperspectral imaging parameters and produce a series of images to be acquired at a series of retardances at a series of retardance times, a hyperspectral imaging component having an input polarizer to polarize an incoming beam of light, a liquid crystal variable retarder to receive the polarized beam of light and to produce wavelength-dependent polarized light, an output polarizer to receive the wavelength-dependent polarized light and to convert polarization state information into a form detectable as light intensity, a voltage source connected to the liquid crystal variable retarder, and a retardance controller. The retardance controller receives the series of retardances at a series of retardance times and produces a series of voltages at a series of voltage times to apply to the liquid crystal variable retarder. A focal plane array, synchronized with the retardance controller, receives the light in a form detectable as light intensity and converts the light to a series of images.

    Abstract: A nanocalorimeter device includes a substrate having test cells, each test cell comprising a sample location. Each sample location includes a reaction surface suitable for an enthalpic reaction of constituents of liquid droplets, droplet movement and configured to merge the droplets, and a layer of thermochromic material thermally coupled to the reaction surface. The thermochromic material is configured to exhibit a spectral shift in light emanating from the thermochromic material in response to a change in temperature of the merged droplets.

    Abstract: A device includes a spatial filter arranged in a Cartesian coordinate system having orthogonal x, y, and z axes. The spatial filter has mask features that are more light transmissive and mask features that are less light transmissive. The mask features are arranged along the x-axis in the flow direction of a flow path. A detector is positioned to detect light emanating from at least one object in the flow path, the object having a width along the y-axis, a thickness along the z-axis, and a length along the x-axis. Light emanating from the object is time modulated according to the mask features as the object moves along the flow path. The detector is configured to generate a time-varying electrical signal in response to the detected light that includes information about the width or thickness of the object.
