Fourth International Conference on Photonics and Optical Engineering, 2021
Partial coherent imaging, which provides high robustness and twice the imaging resolution of the coherent diffraction limit, has become a hot research method in quantitative phase imaging. Asymmetric illumination is one of the most common methods to generate phase contrast for weakly absorbed samples. By establishing a strict intensity-phase model, the

Quantitative phase analysis in electron holographic interferometry
Applied Optics, 1987Holographic interferometry in an electron microscope and its phase analysis technique are described. The fringe scanning method is used to gain high sensitivity in phase detection. An example of measuring a magnetic field of a fine particle is presented.

Chapter 11. Quantitative Phase Analysis
2008Measurement of the elemental composition of materials is a relatively mature art. In the natural world there are 92 elements with methods for their quantitative determination generally well established and, in many cases, the subject of internationally accepted standards.

The phase of the photoacoustic signal is of prime importance for obtaining accurate optical absorption coefficients using the photoa-coustic technique. Variations in the spectrometer or the photoacoustic cell parameters between the measurement of the sample spectrum and the carbon black reference spectrum are the main source of phase shifts.

Methodology of quantitative phase analysis
1995The basic equations of quantitative phase analysis, which relate the X-ray intensity to the abundance of a phase in a specimen, were derived in Chapter 2 for various diffractometric schemes. In the forthcoming discussion, we will concentrate on Bragg-Brentano reflection focusing, since this is the most widely used diffractometric arrangement.

Quantitative phase analysis using the Rietveld method
Journal of Applied Crystallography, 1988Quantitative phase analysis of multicomponent mixtures using X-ray powder diffraction data has been approached with a modified version of the Rietveld computer program of Wiles & Young [J. Appl. Cryst. (1981), 14, 149–151]. This new method does not require measurement of calibration data nor the use of an internal standard; however, the approximate ...

Practical aspects of quantitative phase analysis
1995In the previous chapters, we discussed the basic techniques and instrumentation for quantitative diffractometry. We now come to the next step in QXRD—the practical realization of the theoretical concepts outlined earlier. In other words, we have to delineate the techniques and conditions required to carry out this task with acceptable precision and ...

A computer X-ray quantitative phase analysis
Journal of Applied Crystallography, 1983A computer-based method of X-ray quantitative phase analysis which utilizes the whole powder diffraction pattern including overlapping diffractions is described. The measured intensities are compared with those obtained from the calculations based on single-crystal investigations.
