    Abstract: Catadioptric projection systems, devices and methods, including a lens, an illumination source and a reflector, arranged to pass light through a medium and focus the light onto a surface, with a vibration source disposed proximate the medium to impart frequencies on the medium to effect movement of the medium, which may be oscillations, patterns or other movements. The vibration source may be a transducer, audio speaker. The illumination source includes one or more illuminators that may be configured as one or more LEDs, and passes through the lens and provides illumination from one side of the lens, to direct the illumination of projected light through the medium and onto the reflector surface, where the light is reflected off of the mirror surface and back through the medium, through the lens, and focused onto a surface. The device is configured with control circuitry for operating the transducer and LEDs.

    Abstract: Systems and methods are disclosed for bonding a plurality of transducers to an optical element by placing each transducer on a moveable pedestal mounted on a piston; temporarily securing each transducer to the moveable pedestal; applying an epoxy to a plurality of steps on a deflector surface; placing the piston with the transducers over the plurality of steps; actuating the piston and moving each moveable pedestal to contact the transducer with the epoxy; releasing the transducer from the moveable pedestal; and curing the epoxy to secure the transducer to the steps.

    Abstract: An acousto-optic modulator system for protecting a photoreceptor from an incident laser beam from a laser source includes a transducer array that is connected to a glass portion. The glass portion is arranged in a predicted path of the laser beam between the laser source and the photoreceptor. An electronic control unit (“ECU”) selectively energizes the transducer array and causes the transducer array to emit sound pressure waves into the glass portion. The sound pressure waves have predetermined oscillation characteristics that change a refractive index of the glass portion to diffract the beam. A camera system includes the transducer array, the ECU, and a camera having an image sensor and an external lens positioned in the predicted path. A host aircraft includes the photoreceptor, fuselage, one or more wings, the glass portion, the transducer array, and the ECU.

    Abstract: A laser system for creating patterns on clothing includes a laser source; a phased array acousto-optic deflector (AOD) configured to control the direction and intensity of the laser beam; a computer comprising software for reading input files containing pattern designs and controlling the AOD to direct the laser beam according to the pattern designs; a fabric preparation station for washing and preparing fabric before laser treatment; a post-laser wash station for removing debris from the fabric after laser treatment; and a clothing finishing station for applying finishing touches to the fabric. The AOD includes an optical element having a surface with one or more steps formed thereon; a conductive layer formed on the surface with the steps; one or more crystals secured to each step; and electrodes positioned on each surface of each crystal.

    Abstract: A distributed weak grating array sensing system and method with multiple demodulation modes are provided for optical fiber sensing. The distributed weak grating array sensing method includes: amplitude modulating, by an acousto-optic modulator, a laser light to form a double-pulse light satisfying a preset requirement; linearly phase modulating, by a phase modulator, a phase of front pulse light or rear pulse light of the double-pulse light; amplifying double-pulse light after amplitude modulation and phase modulation, and introducing the double-pulse light into a grating array; allowing reflected light of the double-pulse light on adjacent gratings to superimpose and form interference light; introducing the interference light into a photoelectric detector; acquiring, by an acquisition card, data; locating a disturbance through the amplitude fluctuation; accurately acquiring a sampling number corresponding to 2π; and selecting π/2 phase difference demodulation, 2π/3 phase difference demodulation, π/4 phase difference demodulation, proposed N-step phase difference demodulation as required.
