The invention relates to a method for transferring a MEMS onto a substrate. The invention relates to a method for transferring a MEMS onto a substrate. During the transferring method, an intermediate vibration absorption block (10) is interposed between the MEMS (20) and the substrate (8). The intermediate vibration absorption block (10) has such a minimum height that the distance between the MEMS (20) and the substrate (8) is higher than 100 μm. Advantageously, the dimensions of the intermediate vibration absorption block (10) are chosen with the aim of more effectively absorbing the mechanical vibrations from the substrate. The transferring method according to the invention thus makes it possible to increase the MEMS accuracy while limiting the risk of damage, or even breakage thereof, in particular when said MEMS is subjected to a vibratory environment of a few thousands of Hertz.

The invention relates to a method for determining a difference in depth or a lateral distance in relation to the vertical between two points (O2, M) of an underwater environment (E), in particular by measuring a propagation time of a sound wave. Said determination is based on a single-layer model of the environment in which the wave is supposed to propagate in a straight line along an effective propagation direction, at an average speed that is independent of the propagation direction. The invention also relates to a method for determining the profile of said average speed based on the measurements of differences in depths per se, a determination of the local speed profile over the variation interval of the sounded depths, and a related sonar system (10).

Abrégé

Disclosed is a system for the interferometric measurement of a physical parameter, including an amplified spontaneous emission light source, optically connected to a Sagnac ring interferometer, and two detectors, each supplying a measurement signal representative of the light output from the interferometer, and a reference signal representative of the light output emitted by the source, which is impaired by an excess relative intensity noise. This measurement is obtained from a difference between the measurement and reference signals, weighted by a weighting coefficient which is controlled to minimise the statistical deviation of an additional weighted difference between signals obtained by demodulating the measurement and reference signals by way of an additional digital demodulation sequential code insensitive to the parameter. Also disclosed is a gyroscope including such a measuring system.

Disclosed is a broadband underwater acoustic transceiver device. The device can be used in particular for positioning, detection, range finding or underwater acoustic communication. The device coaxially combines, within a transceiver device, a Tonpilz transducer and a FFR transducer, the FFR being arranged in front of the transmission face/horn of the Tonpilz transducer. In such a configuration, the Tonpilz horn also acts as reflective tape for the FFR transducer, forming a common tape-horn element. Furthermore, an annular baffle surrounding the Tonpilz pillar creates a Helmholtz cavity for broadening the emission band towards the low frequencies.
