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 main objective of this book is to present the basic theoretical principles behind modern
fringe-pattern analysis as applied to optical metrology. In addition to this, for the …

The simple filtering procedure, high spatial resolution, and low computation time benefits of
Fourier normalized-fringe analysis are verified. For this, both the fringe-pattern normalization …

In most simultaneous phase shifting interferometry (SPSI) systems, a group of phase shifting
interferograms are captured simultaneously at the different physical locations to retrieve the …

We present a simple and novel algorithm for the phase extraction from a single
interferogram based on the spatial processing of interference patterns. This new evaluation …

A simple interferometer for the characterization of axicon lenses is presented. The phase
cone acquired by a wave propagating through an axicon, when interfered with a collinear …

The four phases stitching algorithm is proposed to demodulate the circular carrier
interferogram, which can eliminate the sign ambiguity and avoid serious local errors in the …

An efficient method to remove carrier and aberration during phase processing from off-axis
holography is proposed using a specimen-free hologram (SFH). One modulated carrier …

We present a new interferometric method for shape measurement of hollow cylindrical
tubes. We propose a simple and robust self-referenced interferometer where the reference …

We have been working in the interferometric analysis of the ablation profile obtained with
different techniques of refractive surgery, applied directly on hard contact lenses. We have …
