Özet

We demonstrate that the fractional-order Fourier transformation is a suitable method to analyze the diffraction patterns of particle field holograms. This method permits reconstruction of in-line digital holograms beyond the Fraunhofer condition (d(2)/lambdaz similar or equal to 10), We show that the diameter of spherical particles is measured with good accuracy. Simulation and experimental results are presented. (C) 2002 Optical Society of America.
