Abstract: In-line holography to create images of a specimen, such as one or more particles dispersed in a transparent medium. Analyzing these images with results from light scattering theory yields the particles' sizes with nanometer resolution, their refractive indexes to within one part in a thousand, and their three dimensional positions with nanometer resolution. This procedure can rapidly and directly characterize mechanical, optical and chemical properties of the specimen and its medium.

Abstract: A method and system for performing three-dimensional holographic microscopy of an optically trapped structure. The method and system use an inverted optical microscope, a laser source which generates a trapping laser beam wherein the laser beam is focused by an objective lens into a plurality of optical traps. The method and system also use a collimated laser at an imaging wavelength to illuminate the structure created by the optical traps. Imaging light scattered by the optically tapped structure forms holograms that are imaged by a video camera and analyzed by optical formalisms to determine light field to reconstruct 3-D images for analysis and evaluation.

Abstract: A method and apparatus for providing content in a broadcast system is provided. Upon receipt of a request for synchronization from a mobile terminal, a set-top box creates a recommended content list based on user information received from the mobile terminal and delivers the recommended content list to the mobile terminal. The set-top box receives from the mobile terminal a content list, selected from the recommended content list and included in a Personal Information Management System (PIMS) updated using the recommended content list. The set-top box determines whether a user of the mobile terminal intends to view content from the received content list at a start time of the content. Upon receipt of view acceptance information from the mobile terminal, the set-top box sends a request for the content to a service provider at the start time, receives the requested content from the service provider, and provides the received content to the mobile terminal.
