In this work, we propose a dual-wavelength in-line digital holographic microscopy (DHM) configuration in order to eliminate the conjugate image and reach the maximum resolution of CCD. By using this configuration, two holograms are acquired in one sh

Digital Holographic Microscopy (DHM) typically uses either Michelson or Mach–Zehnder interferometers as interferometric tools to attain digital holograms. These interferometers need not only good optical alignment in order to compensate the spheric

This work focuses on the implementation of a structured light projection technique for the analysis of the 3D vibration modes of microsamples. The Talbot image of a Ronchi grating is projected onto the sample surface passing through one of the object

Two methods to measure the diffusion coefficient of a species in a liquid by optical interferometry were compared. The methods were tested on a 1.75 M NaCl aqueous solution diffusing into water at 26 °C. Results were D = 1.587 × 10−9 m2 s−1 wit

A novel phase extraction method for fringe patterns with carrier frequency and with slow variation with time is presented. It is based on the Fourier-transform method and on the quotient of the two adjacent frame fringe patterns. The fringe patterns

A technique for measuring the object shape is presented. In this technique, the object is scanned by means of a light line. From the scanning, a set of images is captured by a CCD camera. The object surface is recovered by processing these images. To

The phase-shifting technique is widely used to measure the whole-field phase-difference from fringe patterns generated by interferometry. The reasonable maximum errors, and in turn the uncertainties of the measured phase-difference values, depend mai

Electronic speckle pattern shearing interferometry (ESPSI), also known as shearography, is a whole-field optical technique used to measure approximately the fields of displacement derivatives. The accurate measurements of these derivatives have two p
