    Abstract: This disclosure provides a portable hemostatic bandage system, which comprises two formulations comprising siloxanes and blowing gas generating agents as well as a dual container device, optionally a dual syringe applicator, for in situ construction of a sponge-like polymer foam as hemostatic bandage material. Two formulations kept separately in a dual container device react instantly with each other when forced to mix, and as a result, decomposition of hydrogen peroxide occurs to generate a blowing gas O2 and heat, and consequently siloxane polymer curing occurs to form polymer foam inside the dual container device. When the blowing foam is applied to a bleeding wound, it forms a sponge plug within a few minutes to control hemorrhage. This portable hemostatic bandage system can be easily used at ambient temperatures, and it is a cost-effective method to control hemorrhage.

    Abstract: A phase modulation device may include two rotated chirped volume Bragg gratings (r-VBGs), where the two r-VBGs are spatially separated along a separation direction oriented at a nonzero degree angle to the grating vectors, and further includes a phase modulator between the two r-VBGs with a spatially non-uniform phase distribution in a plane orthogonal to the separation direction. A first of the two r-VBGs may reflect portions of an input beam propagating towards the phase modulator as spectrally-spread beam. A second of the two r-VBGs may reflect portions of the spectrally-spread beam satisfying the Bragg condition into the incidence direction, where the second r-VBG is positioned to provide that the Bragg condition is satisfied for different wavelengths at different locations of the first r-VBG along the incidence direction to provide that the spectrally-spread beam is spectrally recombined into an output beam.

    Abstract: A spectrometer may include a rotated volume Bragg grating (r-VBG) within a volume of a material having an input face, where the r-VBG reflects portions of input light propagating through the input face that satisfies a Bragg condition for wavelengths within a spectral band, where a period of the r-VBG along the grating vector is chirped to vary along the grating vector to provide that the Bragg condition is satisfied for different wavelengths at different depths, and where a spectrum of the input light is spatially resolved in the reflected portions of the input light by the r-VBG. The spectrometer may further include a multi-pixel detector configured to receive the reflected portions of the input light from the r-VBG, where the multi-pixel detector is configured to output spectral data indicative of the spectrum of the input light within the spectral band.

    Abstract: An optical display system and an electronics apparatus are disclosed. The optical display system comprises: an image source, which generates image light; and an optical combiner, which includes two reflection-type polarization volume lenses working in a Bragg regime, wherein a first reflection-type polarization volume lens of the two reflection-type polarization volume lenses diffracts the image light of a first polarization to a first image and transmits the image light of a second polarization, and a second reflection-type polarization volume lens of the two reflection-type polarization volume lenses diffracts the image light of a third polarization to a second image and transmits the image light of a fourth polarization, the optical combiner outputs the first image and/or the second image as an combined image.
