摘要： Electrophoretic displays (100, 400) comprise suspensions in one or more bodies of liquid (116, 418, 426) of reflective particles (118, 420), and photoluminescent particles (120, 422). The one or more bodies of liquid are located between a front wall (104, 402) and a back wall (102, 404). Electrodes (128, 129, 410, 412) and optionally a transparent ground plane layer (124) are provided for applying electric fields to the suspensions according to image information. The reflective particles and the photoluminescent particles are characterized by the electrophoretic mobilities of the same sign, and therefore move in the same direction in response to applied fields. A source of radiation (140, 428) capable of exciting photoluminescence of the photoluminescent particles is optically coupled to the liquid suspensions. An optical filter layer is optionally located at the front of the displays. The display is capable of operating under a wide range of ambient light conditions.

摘要： A method and ultra-compact system has been developed for illuminating and detecting the surface topography of an object such as the finger (4) of an individual. The system (8) is capable of producing high-contrast images which can be electronically transmitted in real-time, or stored using electronic or photographic recording devices. Light traveling within a light transmitting substrate (2) is redirected by a slanted-fringed light diffractive grating preferably embodied within a volume hologram (3). The volume hologram (3), either of the reflection or transmission type, is attached to the light transmitting substrate (2). and functions to diffract light striking thereupon and illuminate an object having topographical surface structure. After being spatially and intensity modulated in accordance with topographical details of the illuminated object, the insulated light passes back through the light transmitting substrate (2) and the volume hologram (3), onto an image detection array. for subsequent analysis. Each of the disclosed embodiments has a compact geometry suitable for use in diverse object identification applications.

摘要： A method and system for recording and displaying grazing-incidence (i.e., steep reference beam angle) holograms supported on a substrate having thin edge-illuminatable geometry. The system and process of the present invention uses thin edge-illuminated substrates that facilitate optimal coupling of the reference light beam at steep angles approaching grazing incidence, while maximizing the contrast of the slanted fringe structures thereof. A recording medium is in direct contact with a thin substrate whose refractive index is greater than the bulk refractive index of the recording medium. At the substrate interface, the recording medium has a gradient-type index matching region, created by exposure of the recording medium to reference beam illumination, prior to the further application of an object beam to create a fringe pattern.
