    摘要： A radially symmetric iterative discrete on-axis hologram has a high diffraction efficiency for a correspondingly small f-number. The radially symmetric hologram has a plurality of concentric constant radial phase fringes. Each fringe has a predetermined plurality of radial phase rings and each fringe corresponds to a predetermined plurality of radial phase transition points and a radial phase value between the radial phase transition points. The radially symmetric iterative discrete on-axis hologram also has radial phase fringes with a predetermined number of phase levels, at least two adjacent fringes have a phase level difference which is greater than one and less than the predetermined number minus one. The radially symmetric iterative discrete on-axis hologram is fabricated by determining a plurality of concentric fringes of constant phase with a plurality of radial phase transition points and radial phase values between the radial phase transition points for each concentric fringe. The plurality of radial phase transition points and radial phase values are repeatedly optimized to obtain optimized radial phase transition points and optimized radial phase values which maximize the diffraction efficiency. A radially symmetric hologram with concentric fringes of constant radial phase corresponding to the optimized radial phase transition points and the optimized radial phase values is then fabricated using known fabrication techniques.

    摘要： An integrated optical apparatus includes an optically transparent substrate with a light source and a detector mounted adjacent thereto. The substrate includes an optical element in a transmit path from the light source to a remote target. The optical element splits the light into more than one beam. A detector receives beams reflected by the target. All optical elements needed to create the more then one beam, direct the more than one beam onto the target and direct the more than one beam from the target to the detector are on the substrate and/or any structure bonded to the substrate. Preferably, the optical element provides sufficient separation between the more than one beam such that each beam is delivered to a unique respective light detecting element of the detector. The return path from the remote target to the detector may include an optical element for each beam or no optical elements. An additional substrate may be included and bonded to the substrate. The active elements may be bonded to a bottom surface of the substrate, either directly or via spacer blocks, or may be provided on a support substrate, which is then bonded, either directly or via spacer blocks, to the substrate.
