  • Multi-passage cavity of an optical device for spatial manipulation of luminous radiation
    Patent number: 11579437
    Abstract: A multi-passage cavity made up of the assembly of a planar mounting and first and second reflective optical elements each having a main face arranged opposite one another, the main face of at least one of the optical elements being microstructured to modify the phase of incident luminous radiation that is reflected several times on each of the optical elements to form transformed radiation, the multi-passage cavity includes precisely three assembly interfaces.

  • Monolithic cavity for light manipulation
    Patent number: 11391889
    Abstract: A device for manipulating a light radiation by reflecting the light radiation multiple times on at least two reflecting surfaces of a monolithic block made of homogenous transparent material comprises a first and second zone on surfaces of the block for injecting the light radiation to be manipulated, and for extracting the light radiation after manipulation. At least one of the reflective surfaces is micro-structured to impart a determined spatial phase transformation.
