    Abstract: A terahertz (THz) spectral imaging system includes a THz 2D imaging camera, a tunable THz bandpass filter before the THz camera, and a broadband THz light source. The tunable THz bandpass filter includes a visible or infrared laser source, a spatial light modulator modulating the light to generate a spatially structured light pattern, and a semiconductor plate onto which the light pattern is projected. The light pattern generates carriers in the semiconductor plate to turn it into a metamaterial THz bandpass filter, which is tunable by changing the light patterns. A controller controls the light patterns and the THz camera in a timing sequence to acquire multiple 2D THz images at different THz frequencies. Such THz spectral image data can be further combined with visible images and LiDAR images in a security surveillance system to automatically detect security threats using image fusion and deep learning techniques.

    Abstract: A device for producing polarized light includes a plurality of photonic crystal grid structures on a substrate. The plurality of photonic crystal grid structures includes one or more structured regions for the transmission of polarized blue light, polarized green light, and polarized red light. A green quantum dot layer is substantially positioned on the one or more structured regions for the transmission of polarized green light and a red quantum dot layer is substantially positioned on the one or more structured regions for the transmission of polarized red light. A blue light emitting diode array is disposed on the polarized light device such that the emission from the blue light emitting diode array facilitates the emission of red and green light from the red and green quantum dot layers.

    Abstract: A method that includes coating a photopolymer layer on a substrate to create a photopolymer coating, passing light from a light source through an aperture array to create a light interference pattern, and exposing the photopolymer coating to the light interference pattern to create cross-linked regions and non-cross-linked regions within the photopolymer coating. The method further includes creating a thermal insulation film product by dissolving the non-cross-linked regions to create a porous thermal insulation film disposed on the substrate.
