    • To provide a random device for randomly testing logic circuits, particularly microprocessors, it is necessary to use a device for transforming the occurrence probability of logic vectors to produce vectors sequences having time-changing probabilities. Such a device comprises a memory or an equivalent circuit to which are applied input logic vectors (Ve1, Ve2... Vn) having respective occurrence probabilities which are different or the same and containing, in the respective areas of different range, the different categories of output vectors (Vs1, Vs2... Vsi). Thereby the occurrence probability of a predetermined output vector (Vs1, Vs2... Vsi) depends both on the range of the memory area wherein said vector is stored, that is to say the number of elementary positions or eight-bit bytes which are included within said area, and on the respective probabilities (pr1, pr2... prn) of the input vectors (Ve1, Ve2... Ven) corresponding to the addresses of the elementary positions (m1, m2... mn) of the area of the memory in question.
    • 为了提供用于随机测试逻辑电路,特别是微处理器的随机设备,需要使用用于变换逻辑矢量的出现概率的设备来产生具有时变概率的向量序列。 这样的装置包括存储器或等效电路,其中施加了具有不同或相同的各自出现概率的输入逻辑向量(Ve1,Ve2 ... Vn),并且在不同范围的各个区域中包含不同类别 的输出矢量(Vs1,Vs2 ... Vsi)。 因此,预定输出向量(Vs1,Vs2 ... Vsi)的发生概率都取决于存储了所述向量的存储区域的范围,也就是说,包括基本位置的数量或包括8位的字节 在与所述区域的基本位置(m1,m2 ... mn)的地址相对应的输入向量(Ve1,Ve2 ... Ven)的各自概率(pr1,pr2 ... prn) 有问题的记忆的区域。

    • The invention concerns an optical component of polarizing modulation, a polarimeter and a Mueller ellipsometer comprising this optical component. The optical component modulates an incident light beam (10) linearly polarized and sends back a modulated beam (11). It comprises a coupled phase modulator (6B) modulating twice successively the incident beam, the two modulations being at the same frequency omega /2 pi and being coupled by a system (61) modifying the state of polarization of the light between the two modulations. The ellipsometer comprises means for sensing a measuring beam sent back by a sample, which receives the modulated beam, and a processing unit. The sensing means include a polarimeter generating n measured quantities representing the states of polarization of the beam and the processing unit generates by Fourier transform m values for each of these quantities, with n x m >/= 16 and m >/= 4, for simultaneously acceding to the sixteen coefficients of the Mueller matrix of the sample.
