摘要

Method of measurement of the tridimensional objects by shadowgraph to a single optical, using the laws of the propagation of the lumière.selon the invention, in order to measure an object (32), for example a hollow sphere, translucent or transparent to visible light, with the aid of the laws of snell - descartes, relating to the propagation of light through the object, it establishes an equation which connects the parameters opto - of the object to the result of an observation made directly on an image of the object, this image is acquired by observing this object by shadowgraph to a single view, it acquires this image, the observation, and is determined at least one parameter geometrical or optical of the object with the aid of the equation and the result of the observation.
