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： The field of the invention is that of the detection of high frequency electromagnetic waves. The invention can be applied to a very wide range of bandwidths, but the preferred field of application is the terahertz frequency domain. The core of the detection device involves a so-called active material with an absorption coefficient in the optical domain that depends on the intensity of the terahertz signal to be detected. By measuring the variations of the absorption coefficient by means of an optical probe, the intensity of the terahertz signal is thus determined. By this means, a frequency translation is performed in a frequency domain where the measurement no longer poses technical problems. It is notably possible to improve the sensitivity of the detector by having antennas suited to the active medium, by using semiconductor or quantum well materials. In this case, it is also possible to produce a matrix or an array of terahertz sensors, thereby enabling either terahertz imaging or terahertz spectroscopy to be carried out.
摘要翻译：本发明的领域是检测高频电磁波的领域。本发明可以应用于非常宽的带宽范围，但是优选的应用领域是太赫兹频域。检测装置的核心涉及所谓的活性材料，其在光学域中的吸收系数取决于待检测的太赫兹信号的强度。通过利用光学探针测量吸收系数的变化，可确定太赫兹信号的强度。通过这种方式，在频域进行频率转换，其中测量不再造成技术问题。通过使用适合于活性介质的天线，通过使用半导体或量子阱材料，显着地可以提高检测器的灵敏度。在这种情况下，也可以产生太赫兹传感器的矩阵或阵列，从而能够进行太赫兹成像或太赫兹光谱学。

摘要： A synchronization device which synchronizes signals transmitted from a transmitter to receivers. The transmitter includes a generator for generating a synchronization signal having a recurrence period substantially equal to the minimum resolution of the journey time between the transmitter and the receiver. Each receiver includes a controllable delay for delaying the synchronization signal and a synchronization loop downstream of the delay. The synchronization loop includes a semi-reflecting plate, a correlator and a device for slaving the delay depending on the correlation. A signal received by the receiver is synchronized when the correlation function of the two successive recurrences of the synchronization signal passing through the semi-reflecting plate is at a maximum. The device may be used for accurate synchronization of information distributed from a transmitter to mutually remote receivers, for example for operating complex electromagnetic or optical rigs.
