    Diffraction effects and special advantages in electronic heterodyne moire deflectometry (1986)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: Effects of diffraction on the performance of electronic heterodyne readout of moire fringes are investigated. The sensitivity, accuracy, and resolution of the system are calculated, and it is shown that these features are significantly improved compared with the conventional intensity moire readout technique. The sensitivity of the system can be tripled without changing the distance between gratings. The system was evaluated experimentally by measuring the refractive-index derivatives of a weak phase object consisting of a large KD(asterisk)P crystal. Effects of nonlinear fringe modulation were studied both theoretically and experimentally. It is shown that in this case the electronic phase is not linearly related to the fringe shift, and calibration of the system is necessary.

    Deferred electronic heterodyne moire deflectometry: A method for transient density fields measurement (1989)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Effects of spherical aberrations of the mirror used in the moire system on the angular resolution of the system are investigated. It is shown that the spherical aberrations may reduce significantly the performance of the conventional moire deflectometer. However, due to the heterodyne procedure, this is not the case with the heterodyne moire system. A moire system with a constant speed moving grating is demonstrated. It is shown that the system readout is linear and the system does not need calibration. In addition, the repeatability of the measurements is improved in this system as compared to the sinusoidally moving grating setup. The problem of the photographic plates alignment is solved by using a mechanical system in which the plate is held firmly throughout the experiment and accurately replaced after removing for photographic processing. The effect of a circular detector's aperture size on readout was tested. It is shown that the spatial phase variations, observed when scanning along a straight moire fringe, may considerably be reduced. At present we may say that both the on-line and the deferred heterodyne moire techniques may reliably be used. The errors of phase readings are 1 deg and 5 deg for the on-line and deferred methods. The total error due to subtraction of two readings at each position is, therefore, 1.4 deg and 7 deg, respectively. Further research for improving the deferred system is suggested.

    Performance of moire deflectometry with deferred electronic heterodyne readout (1987)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: The effects of diffraction and nonlinear photographic emulsion characteristics on the performance of deferred electronic heterodyne moire deflectometry are theoretically and experimentally investigated. The intensity transmission distribution of the transparency, the moire image, the heterodyne readout, and the spatial and angular resolution are analytically discussed. The deferred electronic heterodyne technique is evaluated by measuring small fringe shifts caused by a weak phase object. It is found that this technique can be applied for accurate and sensitive readout of moire fringes of unsteady phase objects. The theoretical study shows that the accuracy and sensitivity of the system are weakly affected by diffraction and nonlinear photographic emulsion characteristics. Nonlinear recording does not affect the spatial resolution of the system.
