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 …

A compact and efficient algorithm for digital envelope detection in white light interferograms
is derived from a well-known phase-shifting algorithm. The performance of the new …

The paper reviews the main numerical techniques that have been developed to carry out
fully automated analysis of fringe patterns resulting from solid mechanics experiments …

The field of optical metrology offers a wealth of both practical and theoretical
accomplishments, and can cite any number of academic papers recording such. However …

We present a new digital two-step reconstruction method for off-axis holograms recorded on
a CCD camera. First, we retrieve the complex object wave in the acquisition plane from the …

Where conventional testing and inspection techniques fail at the micro-scale, optical
techniques provide a fast, robust, and relatively inexpensive alternative for investigating the …

A simple and robust setup for femtosecond time-resolved imaging interferometry of surfaces
is described. The apparatus is capable of measuring both very small phase shifts (∼ 3× …

Microscopic interferometry is a powerful technique for the static and dynamic
characterization of micromechanical devices. In this paper we emphasize its capabilities for …

A novel optimized heterodyne method that recovers the complete electric field of any four-
wave mixing signal at its point of origin is demonstrated. A tracer pulse is sent along the …
