Journal ArticleDOI
Parallel quasi-phase-shifting digital holography
TL;DR: In this article, a parallel quasi-phase-shifting digital holography technique was proposed for noiseless instantaneous measurement of three-dimensional objects using a phase shifting array.
Journal ArticleDOI
Parallel three-step phase-shifting digital holography
TL;DR: In this article, the authors proposed a parallel three-step phase-shifting digital holography, which is capable of noiseless instantaneous measurement of three-dimensional objects based on phaseshifting interferometry.
Journal ArticleDOI
Experimental demonstration of parallel two-step phase-shifting digital holography.

TL;DR: In the experiment, the unwanted images, the zero-order diffraction wave and the conjugate image, are removed from the reconstructed image of objects by the system, while the images superimpose on the image of Objects reconstructed by Fresnel transform alone.
Journal ArticleDOI
Image quality improvement of parallel four-step phase-shifting digital holography by using the algorithm of parallel two-step phase-shifting digital holography.

TL;DR: An algorithm is proposed that can improve the quality of the reconstructed image from the single hologram recorded by the optical system of the parallel four-step phase-shifting digital holography and eliminate ghosts.
Journal ArticleDOI
Moving picture recording and observation of three-dimensional image of femtosecond light pulse propagation.
TL;DR: H holography technique provides the means for observation of a temporally and spatially continuous moving picture of light itself and also enables the analysis of various kinds of ultrafast phenomena.
