Abstract
The invention is a method for estimating a representative volume of particles of interest () immersed in a sample, the sample extending in at least one plane, referred to as the sample plane (P), the sample comprising a sphering agent, capable of modifying the shape of the particles, the method comprising the following steps: a) illuminating the sample by means of a light source (), the light source emitting an incident light wave () propagating towards the sample () along a propagation axis (Z); b) acquiring, by means of an image sensor (), an image (I) of the sample (), formed in a detection plane (P), the sample being arranged between the light source () and the image sensor (), each image being representative of a light wave () referred to as an exposure light wave, to which the image sensor () is exposed under the effect of illumination; c) using the image of the sample (I), acquired during step b), and a holographic propagation operator, to calculate a complex expression (A (x, y, z)) of the exposure light wave () in different positions relative to the detection plane; the method comprising a step of estimating the representative volume (AA) of the particles of interest () depending on the complex expressions calculated during step c).
