摘要
The invention relates to a method for determining a three- dimensional particle distribution (6) in a medium (M), comprising: emitting a coherent light beam (9) to irradiate the sample (3); recording an interference image (12) of the scattered light beam (10) and a second part of the light beam (11) that has not been scattered; computing, from the interference image (12), for each one of a plurality of virtual planes (13i) lying within the sample (3), a reconstructed image (14i) of the sample (3), generating for each reconstructed image (14i), a presence image (16i), wherein a value is assigned to each pixel (17) of the presence images (16i) if the corresponding pixel (15) of the reconstructed image (14i) has an intensity value (I) exceeding a threshold value (TH) and if the corresponding pixel (15) of the reconstructed image (14i) has a phase value (Φ) with a predetermined sign (SG).
