摘要
An optical device is formed of a plurality of optical parts arranged on a carrier, at least one optical element of which has a main face provided with a first microstructured zone for intercepting incident luminous radiation propagating along a first determined optical path, the first microstructured zone spatially modifying the phase of the incident luminous radiation according to a determined spatial profile. The first microstructured zone is used to form. via a plurality of reflections or transmissions off/through the one or more optical elements, transformed luminous radiation. The optical device comprises an input stage for guiding the injection of positioning luminous radiation, along a second optical path, and in that the main surface of the optical element includes a second microstructured zone that is configured to reflect the positioning luminous radiation and to back-propagate the positioning radiation along the second optical path.
