We describe a new method to determine the rough size of particles in an in-line hologram. This method relies on a property that is specific to interference patterns in Fresnel holograms: Self-correlation of a hologram provides access to size information. The proposed method is both simple and fast and gives results with acceptable precision. It suppresses all the problems related to the numerical depth of focus when large depth volumes are analyzed. © 2006 Optical Society of America %G English %2 https://ujm.hal.science/ujm-00116991v2/document %2 https://ujm.hal.science/ujm-00116991v2/file/AO_denis_06.pdf %L ujm-00116991 %U https://ujm.hal.science/ujm-00116991 %~ UNIV-ST-ETIENNE %~ INSTITUT-TELECOM %~ ENSMP %~ IOGS %~ CNRS %~ LAHC %~ ENSMP_CMM %~ PARISTECH %~ PSL %~ ENSMP_DEP_MS %~ ENSMP_DR %~ UDL %~ ENSMP-PSL %~ TEST3-HALCNRS
