A portable two-mode probe to be applied against a biological tissue to be examined, the probe including an ultrasonic transducer configured to emit ultrasonic waves into the tissue and to receive ultrasonic waves reflected by the tissue, the transducer extending along a transverse axis; and at least two optodes placed on either side of the transverse axis, such that the transducer extends between the two optodes. Further, each optode includes a casing containing a light emitter configured to emit a light wave toward the tissue, and/or an optical detector configured to detect a light wave scattered by the tissue. The optodes are arranged such that at least one light emitter and at least one optical detector are placed on either side of the transducer, and at least one optical detector has a detection area formed from a semiconductor and connected to a circuit board.

Bimodal ultrasonic probe comprising an optical device for diagnosis

A method for characterizing a particle present in a sample, the sample lying between an image sensor and a light source and the sensor lying in a detection plane, includes illuminating the sample with the light source which emits an incident light wave propagating along a propagation axis, and acquiring an image of the sample with the sensor. The sensor is exposed to an exposure light wave. The image includes a plurality of elementary diffraction patterns each corresponding to one particle. The method also includes reconstructing a complex image representative of a complex amplitude of the light wave on a reconstruction surface passing through the sample, based on the acquired image; selecting a region of interest of the complex image corresponding to a particle of interest; forming an extracted image based on the region of interest; and characterizing the particle of interest depending on the extracted region of interest.
