Abstract: A method for measuring the geometrical structure of an optical component ( 2 ) in transmission, comprises illuminating the optical component by means of a first incident beam ( 8, 10 ), the wavefront of which is known. After the first beam is transmitted by the optical component, its wavefront is measured by deflectometry ( 16, 18 ). The optical component is then illuminated by a second incident beam ( 12, 14 ), the wavefront of which is known. After the second beam is transmitted by the optical component, its wavefront is measured by deflectometry ( 16, 18 ). The geometrical structure of the optical component is then calculated from the measured wavefronts. Measuring light transmitted in two distinct optical configurations allows a calculation by optimizing the two surfaces of the component, without prior knowledge of one of the surfaces. The first and second beams may be different and may illuminate the same surface of the component; thus it is possible to use identical beams and to illuminate each surface of the component in succession.

Abstract: The invention concerns the marking of an object (10) made of translucent synthetic material and its associated reader. The invention is characterised in that it consists in etching cells in the shape of a well (20) such that each etched cell (14) has, embossed on the base (21) of this well (20), at least one protrusion (22). The invention is useful, in particular, for marking an ophthalmic lens.
