Phase contrast metrology using digital in-line holography: General models and reconstruction of phase discontinuities

Autor: Sébastien Coëtmellec, Marc Brunel, Huanhuan Shen, K. Aït Ameur, Denis Lebrun

Publikováno v: Journal of Quantitative Spectroscopy and Radiative Transfer. 126:113-121

General models are developed to describe in-line digital phase contrast experiments. They link analytically the reconstruction process and the different parameters of the set-up. Reconstructions of phase discontinuities are realized using 2 Dimension

Femtosecond digital in-line holography with the fractional Fourier transform: application to phase-contrast metrology

Autor: K. Aït Ameur, Denis Lebrun, Sébastien Coëtmellec, Marc Brunel, Huanhuan Shen

Publikováno v: Applied Physics B. 106:583-591

The possibility to analyze transparent phase objects using femtosecond digital in-line holography is demonstrated. We show that the diffraction patterns produced by the diffraction of 20-fs pulses by pure phase objects can be advantageously processed
