摘要

We present a numerical technique for extended focused imaging and three-dimensional analysis of a micro-nparticle ﬁeld observed in a digital holographic microscope working in transmission. The three-dimensionalnlocalization of objects is performed using the local focus plane determination method based on the integratednamplitude modulus. We apply the refocusing criterion locally for each pixel, using small overlapping win-ndows, to obtain the depth map and a synthetic image in which all objects are refocused independent fromntheir refocusing distance. A successful application of this technique in the analysis of the microgravity par-nticle ﬂow experiment is presented. © 2008 Optical Society of America
