Steerable spatial phase shifting applied to single-image closed-fringe interferograms.
It is well known that spatial phase shifting interferometry (SPSI) may be used to demodulate two-dimensional (2D) spatial-carrier interferograms. In these cases the application of SPSI is straightforward because the modulating phase is a monotonic increasing function of space. However, this is not true when we apply SPSI to demodulate a single-image interferogram containing closed fringes. This...
متن کاملPhotoelastic Fringe Pattern Analysis by Real-time Phase-shifting Method
This paper describes high-speed phase-shifting method for the real-time analysis of isochromatic and isoclinic parameters in photoelasticity. By rotating an analyzer at a constant rate and an output quarter-wave plate at a double rate of the analyzer and recording images by a CCD camera continuously, sequential phase-shifted images which brightness is integrated by sensors are obtained. Then, t...
متن کاملA high precision 3D dynamic measurement prototype system based on color-coded fringe and phase shifting
Accurate dynamic measurement of the 3-D shape of moving objects is a rapidly expanding field, with applications in entertainment, design, and manufacturing. In this work, the two CCD/CMOS cameras are calibrated with a flexible and accurate camera calibration method. Then, a new approach based on color-coded fringe is proposed for high precision 3D dynamic measurement. The method is based on pha...
متن کاملSpatial phase-shifting moiré tomography
A novel spatial phase-shifting method using moiré phenomena is presented. According to our analysis of moiré patterns on the base of scalar diffraction theory there is stable phase shift between fringe patterns of different order filtering. This phase shift is the stric value of and and just depend on the distance between two gratings and the period of gratings. In this spatial phase-sh...
متن کاملNONLINEAR FRAME ANALYSIS BY MINIMIZATION TECHNIQUE
By minimizing the total potential energy function and deploying the virtual work principle, a higher-order stiffness matrix is achieved. This new tangent stiffness matrix is used to solve the frame with geometric nonlinear behavior. Since authors’ formulation takes into account the higher-order terms of the strain vector, the convergence speed of the solution process will increase. In fac...
