Abstract

A method based on digital holography for determining parameters of at least one erythrocyte is provided, said method comprising the steps of: constructing an interference pattern comprising a wave front representative of said at least one erythrocyte arised from the interaction of said at least one erythrocyte and electromagnetic radiation, reconstructing amplitude-and phase information representative of said at least one erythrocyte wave front from said interference pattern and determining the mean corpuscular volume and/or mean corpuscular hemoglobin concentration and/or oxygen saturation and/or mean corpuscular hemoglobin of at least one erythrocyte by combining phase information and amplitude information representative of said at least one erythrocyte.
