We report on the application of time-resolved inline digital holography to study the nonlinear optical properties of quantum dots deposited onto the sample glass. Fresnel diffraction patterns of the probe pulse due to noncollinear degenerate phase mo

We propose a new ptychographic algorithm where the object scanning is performed by the complex-valued probe function, formed in the setup of independent amplitude-phase modulation. The results of numerical experiments demonstrate the effectiveness of

Digital inline pump–probe holography can be applied to estimate parameters of samples’ optical nonlinear properties. Here we propose a mathematical model to describe noncollinear degenerate phase modulation in samples with inhomogeneities of nonl

Interferometry XIX.
One of the problems of interferometric methods is the difficulty of measuring surface shape with sharp boundaries due to the wavelength-limited dynamic range of the measurement. To circumvent this limitation multiwavelength methods or techniques base
