    摘要： A holographic direct-view display system uses holographic integral imaging techniques that is an auto stereoscopic way to reproduce parallax and occlusion. The display is not resolution limited and is scalable to display life size images if desired. The system can be used to transmit 3D depictions of a scene at video and sub-video rates as well as other information, such as images of documents or computer generated images. The images may be captured, transmitted and displayed in real-time (or near real-time) for telepresence or stored for time-shifted display. The system combines integral holography, a pulsed laser to record the hologram at high speed and a dynamic refreshable holographic material such as a photorefractive polymer as a recording media. The system uses techniques to write, read and erase the updateable hologram that allow the holographic material, hence direct-view display to remain stationary throughout each of the processes for continuous presentation of the hologram to the audience. The system may write, read and erase at the same time and continuously to increase throughput. This system may also use additional novel techniques to improve brightness, efficiently implement a full-parallax display and to implement a full-color display in a transmission geometry.

    摘要： Reflection mode VHOEs are designed and fabricated for use in imaging and other applications that require high diffraction efficiency with minimal chromatic aberrations and astigmatism across the bandwidth. A single VHOE acts as a mirror to reflect light (0th diffraction order) at the specified wavelength(s) and bandwidth with a principal ray at an angle equal to an angle of incidence of broadband light. A composite VHOE includes a complementary pair of input and output VHOEs each configured to diffract light into a non-zero Nth order. The input and output VHOEs are positioned in parallel to and offset from each other such that the filtered Nth order beam exits the composite lens on a path at the angle of incidence and parallel to the broadband light while suppressing the unwanted 0th order beam. The composite lens improves suppression of unwanted wavelengths while still achieving minimal chromatic aberration.

    摘要： A Laser Bar Coupler With Improved Brightness of the present invention includes a laser diode array having a number of spaced-apart laser elements, or diodes, each emitting laser radiation. The typical laser diode array laser elements are rectangular in shape, and linearly spaced apart along an axis with the long dimensions of the element along the axis. A number of optical fibers, or waveguides, each having an initially rectangular cross-section are placed adjacent each laser element and sized horizontally and vertically to approximate the rectangular dimensions of the laser element. The proximity and similar sizing of the input end of the rectangular optical fiber to the laser element provides for the near total reception of the optical energy from the laser element into the fiber. As the rectangular fibers extend away from the laser diode array, the optical fibers taper along the slow axis from its input having a dimension approximately the width of the laser emitter, to an output having a dimension which is less than the first dimension. Using this tapering technique, the optical power available at the output has a higher optical density, a significant brightness increase, and has a lower manufacturing cost than alternative and more complicated designs.
