摘要： A system and method of characterizing properties of a medium from a non-linear interaction are include generating, by first and second acoustic sources disposed on a surface of the medium on a first line, first and second acoustic waves. The first and second acoustic sources are controllable such that trajectories of the first and second acoustic waves intersect in a mixing zone within the medium. The method further includes receiving, by a receiver positioned in a plane containing the first and second acoustic sources, a third acoustic wave generated by a non-linear mixing process from the first and second acoustic waves in the mixing zone; and creating a first two-dimensional image of non-linear properties or a first ratio of compressional velocity and shear velocity, or both, of the medium in a first plane generally perpendicular to the surface and containing the first line, based on the received third acoustic wave.

摘要： A compact array of transducers (110, 120) is employed as a downhole instrument for acoustic investigation of the surrounding rock formation. The array is operable to generate simultaneously a first acoustic beam signal (110) at a first frequency and a second acoustic beam signal (120) at a second frequency different than the first frequency. These two signals can be oriented through an azimuthal rotation of the array and an inclination rotation using control of the relative phases of the signals from the transmitter elements or electro-mechanical linkage. Due to the non-linearity of the formation (140), the first and the second acoustic beam signal (110, 120) mix into the rock formation where they combine into a collimated third signal (150) that propagates in the formation along the same direction than the first and second signals and has a frequency equal to the difference of the first and the second acoustic signals. The third signal is received either within the same borehole, after reflection, or another borehole, after transmission, and analyzed to determine information about rock formation.
摘要翻译：传感器（110,120）的小型阵列被用作用于周围岩层的声学研究的井下仪器。阵列可操作以同时产生第一频率的第一声波束信号（110）和以不同于第一频率的第二频率的第二声束信号（120）。这两个信号可以通过阵列的方位旋转和通过控制来自发射器元件或机电连杆的信号的相对相位的倾斜旋转来定向。由于地层（140）的非线性，第一和第二声波束信号（110,120）混合到岩层中，在那里它们组合成准直的第三信号（150），其沿着相同的方向在地层中传播方向比第一和第二信号，并且具有等于第一和第二声信号的差的频率。第三个信号在相同的钻孔，反射后或另一个钻孔中，在传输之后被接收并且被分析以确定关于岩层的信息。
