摘要： The invention concerns an acousto-optic imaging method comprising a step which consists in engraving in a dynamic holographic material (9) a complex index array resulting from the interference of the acousto-optic component of the signal wave (SIG) and a pump wave (PMP) of frequency equal to the frequency of the acousto-optic component.

摘要： The invention relates to a device for emitting at least one tunable monomode laser beam, comprising a tunable master laser which temporarily excites at least one slave laser. The invention is characterised in that the slave laser cavity comprises a dynamic holographic medium and the operating wavelength thereof is programmed or addressed optically by means of the temporary injection of all or part of the beam originating from the master laser. The invention also relates to a device for testing optronic components comprising a plurality of light sources forming a wavelength comb that is characterised in that said source comprises a tunable master laser and a plurality of slave lasers, each comprising a dynamic holographic medium. The invention further relates to an optical addressing source for the formation of a wavelength comb.

摘要： The invention concerns the field of holographic storage units. More particularly, the invention concerns the field of holographic storage units used for bit-by-bit storage of information. It concerns a method for reading data recorded in a holographic material in the form of a hologram obtained by interference of two beams of substantially the same wavelength, and using at least one reflecting layer. The invention is characterized in that it includes the following steps: emitting a light comprising at least said wavelength at said holographic material comprising said hologram; performing a homodyne detection between the signal resulting from the first light diffracted by said hologram and at least one signal selected between the reflected signal and the signal transmitted by said at least one reflecting layer.

摘要： The invention relates to a method for the generation of a carrier for an interferogramme in an interferometry device, either of the real-time holographic interferometry type or the double exposure holographic interferometry type, comprising: a first recording step on a hologramme of a first wave front arriving from an object (8) and generation of a second wave front, with superimposition of the two wave fronts. The invention is characterised in that said two superimposed wave fronts are orthogonally polarised, either naturally or by a modification step and in comprising a step of passing said two orthogonally-polarised wavefronts through a bifringent crystal, a polariser and a detector (9) to cause interference of said two wave fronts. The invention further relates to a device for carrying out said method.
