Journal ArticleDOI
Digital recording and numerical reconstruction of lensless Fourier holograms in optical metrology
TL;DR: Advantages of the lensless Fourier holography setup for the reconstruction of digitally recorded holograms in holographic interferometry are presented and this very simple setup helps to achieve a maximum lateral resolution of the object under investigation.
Journal ArticleDOI
Direct shape measurement by digital wavefront reconstruction and multi-wavelength contouring
Journal ArticleDOI
Wave-front reconstruction from a sequence of interferograms recorded at different planes.
TL;DR: A method by which the phase and the amplitude of a wave front are obtained by processing a sequence of intensity patterns recorded at different planes, which does not use any reference wave.
Journal ArticleDOI
High-speed digital holographic interferometry for vibration measurement
TL;DR: A system based on digital holographic interferometry for the measurement of vibrations is presented and by combination of the deformations recorded at different times it is possible to reconstruct the vibration of the object.

TL;DR: It is experimentally shown that one needs only to feed PhysenNet a single diffraction pattern of a phase object, and it can automatically optimize the network and eventually produce the object phase through the interplay between the neural network and the physical model.
