    Abstract: The present invention relates to a method and apparatus for display of three-dimensional images and production of mega-channel phase-encoded optical communications. In certain embodiments, the device of the present invention allows for the creation and display of real-time, three-dimensional moving holograms. In the present invention, a computed image or virtual model of a real object is stored in a computer or dedicated digital signal processor (DSP). The stored image or model is then converted by the computer or DSP into its Fourier, or holographic, transform. The holographic transform is displayed on a light modulation device that is illuminated by a one portion of a laser emission. The remaining portion of the same laser emission is combined with the holographic transform at a plane to create a three-dimensional image.

    Abstract: An adaptor for holding a micropipette in a spectrofluorimeter includes a base member for holding the micropipette and an optical system for linearly focusing visible or ultraviolet light onto a sample solution held in the micropipette. Specifically, the optical system includes a cylindrical lens which focuses collimated light from a light source into a line along the axis of the micropipette. The optical system also includes a cylindrical quartz lens which recollimates the light that emerges from the micropipette sample holder in a direction which is perpendicular to the direction of the incident light. A spectrometer is provided to receive the recollimated light for measuring the light absorption and light emission characteristics of the sample material held in the micropipette.

    Abstract: A converter for using a spectrophotometer as a fluorometer includes a barrier for blocking the light in a collimated beam from reaching the detector of the spectrophotometer after this light has passed through and excited a sample material. A second detector is positioned to receive any fluorscence from the material which is emitted in a direction substantially perpendicular to the path of the collimated beam. A signal, generated by the second detector in response to fluorescence from the sample material, is modified to drive a second light source with an intensity which is linearlized relative to the generated signal. The detector of the spectrophotometer then receives the output from this second light source to measure the intensity of the fluorescence.
