摘要： The hydrophone has an interferometer structure incorporating a measuring arm in which is provided a very long monomodal optical fibre immersed in the interaction medium in which is propagated the acoustic wave. A phase displacement is induced on the optical wave by the elastooptical effect and said wave is propagated in the fibre by the acoustic wave which creates an acoustic pressure field in the medium. A reference arm establishes a reference optical path and the phase displacement linked with the acoustic wave is detected by interferometry between the two optical waves emerging from the two arms. The optical connections between the source, the optical fibre immersed in the interaction medium, the reference arm and the detector being provided in guided optics in a compact structure.

摘要： A three-color image projector, of the type using several colored light beams with primary colors, with improved luminous efficiency. The projector employs spatial rather than temporal beam modulation. The projector includes a generator producing light in the three spectral bands corresponding to the primary colors (red, green, blue). The generator has at least two light sources (S1, S2), one of which produces multi-spectral band light, and the other is a monochromatic source. By comparison with the prior art, where the white light is produced by a single source, this arrangement avoids, in particular, the elimination of a significant quantity of lumens in the excess primary color.

摘要： Disclosed is an image projector in which a spatial modulation of light is carried out on the two orthogonal components of polarization of light in order to increase the luminous efficiency of the projector. The image projector of the invention includes a light source, a projection screen, a splitter of polarizations splitting the light into two polarized beams having complementary polarizations, two mirrors reflecting the two polarized beams, firstly so as to give them opposite directions and superimpose them on one and the same axis on which a spatial light modulator is positioned and, secondly, to make them pass again through the polarization splitter by which they are superimposed on one and the same axis with one and the same direction and oriented towards the projection screen and/or the light source as a function of their modulation by the spatial modulator.

摘要： Disclosed is a system for the recording of data on optic disks. Presently used optic disks, which can be read with lasers working in wavelengths of the visible region (between 0.5 and 0.8 microns), have a maximum surface storage density of the order of one data bit per elementary zone having an area of about one square micrometer. Beyond this limit, the diffraction does not allow the neighboring zones to be distinguished. A means is proposed to considerably increase the storage capacities: in an elementary zone of a layer, an information bit is written not in the form of a point of absorption of a laser light but in the form of a diffraction grating with a determined pitch. Several diffraction gratings, having pitches different from one another, may be superimposed at the same position, enabling the recording, in one and the same zone, of several information bits. The diffraction gratings are made by a periodic local variation of the optic index of the layer. They are made by a high energy laser beam, out of a material with an index that may vary as a function of this energy. The reading is done by a frequency tunable laser that enables the detection, for different frequencies, of the presence or absence of diffraction gratings.
