Abstract

The present invention is related to a method for characterizing transparent objects (2, 3) in a transparent medium (1), said transparent objects (2, 3) presenting an optical focal area (5, 6) said method comprising the steps of: illuminating a sample comprising the objects (2, 3) to be characterized by means of a directional light (7) source, thereby inducing light intensity peaks (5, 6) at the focal area of said transparent objects; determining at least one characteristic of the light intensity peak (5, 6) induced by said object to be characterized, determining from said light intensity peak (5, 6) at least one property of said object.
