Abstract
This method for detecting at least one particle in a bodily fluid is carried out via a detection system including a light source, a transparent substrate and a photodetector array, the substrate being positioned between the light source and the photodetector. This method includes the placement of a droplet of bodily fluid on the substrate, the illumination of the droplet via the light source, the acquisition of several successive images of the droplet via the photodetector, each image being formed by radiation transmitted by the illuminated droplet and including at least one elementary diffraction pattern, each elementary diffraction pattern corresponding to waves diffracted by a particle upon illumination of the droplet, the identification, via the acquired images of the mobile elementary diffraction patterns, and the counting of moving particles in the droplet, via the identified mobile elementary diffraction patterns.
