  • Fiber-coupled collimator for generating multiple collimated optical beams having different wavelengths
    Patent number: 8238030
    Abstract: An apparatus for providing multiple collimated light beams from optical fibers and the method for producing such beams. The apparatus includes first and second optical fibers that carry light of first and second wavelengths, respectively, a fixture that maintains the fibers in a fixed relationship to one another, and a collimating lens. Light from each of the first and second optical fibers diverges from a face of the fixture. The collimating lens produces first and second collimated light beams that are displaced relative to one another from the light leaving the face. The face of the fixture is positioned to correct for chromatic aberration in the lens.

  • Method of choosing an optimum angle between a reference beam and an object beam to record a hologram
    Patent number: 5850299
    Abstract: A method of choosing an angle between a reference beam and a signal beam in a holographic storage apparatus is presented. The angle between the reference and signal beams can be optimized in light of crosstalk, scattering and wavelength seperation considerations.
