  • Method and device for the optical characterization of particles
    Patent number: 12055471
    Abstract: The present description relates according to a first aspect to a method for measurement of optical properties of at least one particle in a sample (10) and permits, for example, quantitative determination of the complex dipolar polarizability of at least one particle present in a sample. The optical characterization method comprises the illumination of said sample (10) using a light beam, the sample (10) being positioned in the object space of an optical system (120); the acquisition of at least one phase image and at least one intensity image of said at least one particle illuminated by the light beam, the acquisition being carried out in an analysis plane arranged in the image space of the optical system (120); and the determination of at least one optical property of said at least one particle from said at least one phase image and at least one intensity image.
