Abstract

According to the invention, to measure an object (32), for example a hollow, translucent or transparent sphere with respect to a visible light, using Snell-Descartes laws, relating to the propagation of light through the object, an equation is established which associates optogeometric parameters of the object with the result of an observation performed directly on an image of the object, said image being acquired by observing said object, by single-view optical shadowgraphy, said image is acquired, the observation is performed, and at least one geometric or optical parameter of the object is determined using the equation and the result of the observation.
