摘要： An optical architecture enabling the intercorrelation of two instantaneous wideband temporal signals. The beam coming from a monomode laser is used to obtain two carriers (W1, W2) for signals R(t) and S(t) by the use of, for example, integrated optical modulators (mod1, mod2). These two carriers have orthogonal polarizations and are distributed in a 2D structure comprising spatial light modulators as well as polarization separator elements. P.times.P independent channels (Cl to Cn) are thus formed. Their detection on a matrix of photodetectors (modl to modn) makes it possible to obtain, on each of them, the intercorrelation signal for different delays of the signals R(t) and S(t).

摘要： A bidimensional imaging system by echoes including a transmitting array and a receiving array. The transmitting array includes a row of transmitters (E.sub.1, E.sub.2, . . . , E.sub.i, E.sub.N) parallel to a direction Oz and the receiving array includes a row of receivers in a direction Ox. All the transmitters simultaneously transmit signals with different codes. The signals received are demodulated and the real and imaginary components of these signals are applied to two multiplexing circuits (61.1, 61.2). After modulation the multiplexed signals are applied to a Fourier transformation circuit (63), which sequentially supplies reception channels V.sub.k (.theta..sub.k) for the direction referenced by angle .theta..sub.k and which are stored in memories (66.1, 66.2). Other memories (70.1, 70.2) contain signals S.sub.i (.phi..sub.i) transmitted in an angular direction referenced by .phi..sub.i. The two pairs of memories (66.1, 66.2 and 70.1, 70.2) are connected and the signals are applied after modulation to a convolver (61), which supplies signals of the bidimensional image. The imaging system has application to ultrasonic submarine cameras, submarine target classifiers, medical acoustic imaging and non-destructive tests.

摘要： A device for linearly extending the duration of laser light pulses by subjecting the pulses to double diffraction based on a series of variable step gratings placed at right angles to each other. Increased power density is obtained by placing a compression grating at an angle such that each wavelength of light emerging from the compression grating travels an optical path of approximately the same distance, and focusing the emerging light with a lens. Increased amplification is obtained by placing a segmented laser amplifier, one segment aligned with each wavelength of light separated by the double diffraction of the series of variable step gratings and interposed between the series of variable step gratings and the compression grating.

摘要： The invention relates to a programmable transverse filter required for the matched filtering of signals with very wide passband. The signals to be filtered modulate one or more optical carriers (F1) in a modulator (MOD). Each carrier is distributed over several channels by a distributor (DIV). A delay creation circuit (CR1 to CRn) is provided in each channel. These channels are next summed after having been correctly delayed and assigned a coefficient characteristic of the signal to be detected.

摘要： A system realizing various processings of signals, depending on the nature, duration and form of these signals, by means of non-linear interactions between elastic surface waves or between elastic and electromagnetic waves. The system realizes the memorization of the correlation function between a first signal, which is an elastic surface wave, and a second signal which is either an electromagnetic or an elastic surface wave; the reading may be realized with an electromagnetic wave or an elastic surface wave whose angular frequency equals or not that which corresponds to the spatial period of the memorized signal, thus generating correlation or convolution functions.

摘要： The invention relates to a method and device for controlling the amplitude of the wavelength spectrum of ultra-short light pulses emitted by multipass laser amplifiers. According to the invention, a programmable acousto-optic device (8) is introduced into a laser cavity of a multipass amplifier (10), in order to modify slightly the amplitude of the spectrum of the light pulse with each passage, owing to a collinear or quasi-collinear interaction between the light pulse and a sound beam, the result from the filtering being used on the non-diffracted direct light beam from the acousto-optic interaction.
