SURFACE LIGHT-SCATTERING - INTEGRATED TECHNOLOGY AND SIGNAL-PROCESSING

The miniaturization of surface-scattering instruments for measuring vi scoelastic properties is investigated. The concepts are based on the u se of holographic optical elements and integrated optics. Compact form s of optics that provide the necessary spatial and angular selections are devised. Four systems representing increasing levels of integratio n are considered. It is demonstrated that efficient signal and data pr ocessing can be achieved by evaluation of the statistics of the deriva tive of the instantaneous phase of the detector signal.
