In this day of digitalization, you can work within the technology of optics without having to
fully understand the science behind it. However, for those who wish to master the science …

The recording and storage of full-parallax 3D images was and is a recurring goal of science
and engineering since the first photographs were made. To accomplish this, the whole …

The Zernike-polynomials-based modal reconstruction method is an important wavefront
reconstruction method for lateral shearing interferometry. There are four typical Zernike …

Lateral shearing interferometry is a promising reference-free measurement technique for
optical wave-front reconstruction. The wave front under study is coherently superposed by a …

Recording and (computational) processing of complex wave fields offer a vast realm of new
methods for optical 3D metrology. We discuss fundamental similarities and differences …

In this publication, we give a brief introduction into the field of computational shear
interferometry, which allows for determining arbitrary wave fields from a set of shear …

In this contribution, we demonstrate the first referenceless measurement of a THz wavefront
by means of shear-interferometry. The technique makes use of a transmissive Ronchi phase …

A method is proposed for exact discrete reconstruction of a two-dimensional wave front from
four suitably designed lateral shearing experiments. The method reconstructs any wave front …

A high-resolution, high-precision beam-shaping system for high-power-laser systems is
demonstrated. A liquid-crystal-on-silicon spatial light modulator is run in closed-loop to …

Accurate wavefront measurement using double-grating Ronchi lateral shearing
interferometry significantly relies on the accuracy of shear-phase retrieval. Traditional …
