摘要： A light distribution device, for distributing light rays from an ancillary light source onto a scene to be lighted. The device includes a planar waveguide, a recess in the planar waveguide for injecting light rays into the planar waveguide, and a through opening in the planar waveguide for extracting light rays from the planar waveguide. In this way, light can be distributed over a large area, homogeneously and with a thin, easily manufactured device.

摘要： An optical component for an attenuated total reflection multispectral imaging device, which includes a support substrate and at least two planar waveguides, and wherein the planar waveguides and the support substrate are superimposed together, with the support substrate which covers the planar waveguides; each of the planar waveguides includes at least one diffraction grating; and at least two of the planar waveguides have their diffraction gratings which have values of the average pattern distribution pitch which are distinct from each other; the support substrate includes, on one side opposite the planar waveguides, a face forming an exchange interface with a sample; and an exit face of the optical component corresponds to a lateral face of the support substrate.

摘要： An optical component for an attenuated total reflection interferometric imaging device, which includes: a planar waveguide, especially delimited by a front face and a rear face parallel to each other; an injection zone, comprising two input facets, each extending from a side face of the planar waveguide, configured to separate an initial light beam into two sub-beams each deflected in a respective direction when they enter the planar waveguide; and an extraction zone, including two output facets, configured to receive the two sub-beams, and to deflect the same when they exit the planar waveguide, the optical component being configured so that the two sub-beams can interfere with each other after emerging out of the planar waveguide.

摘要： An optical component for an interferometric imaging device, which comprises: an object arm, including a first planar waveguide and a first diffraction grating formed in the first planar waveguide and capable of extracting light from the object arm; a reference arm, comprising a second planar waveguide and a second diffraction grating formed in the second planar waveguide and capable of extracting light from the reference arm; wherein the optical component is configured such that, in use with an optically reflective surface extending parallel to the plane of the optical component between the object arm and the reference arm, at least part of the light extracted from the object arm interferes with at least part of the light extracted from the reference arm.

摘要： A wavelength demultiplexing device configured so as to spatially distributing the spectral contributions of an incident light beam, when in use, and which includes a linear waveguide and a planar waveguide, formed in a coplanar way and adapted to be optically coupled with one another along a coupling line, by evanescent coupling. Such a device may further include diffraction gratings located in the planar waveguide, to extract light out of the latter.
