    • An acoustic microscope comprising a transducer for transmitting acoustic signals towards the surface to be studied, and means for receiving at least one reflected signal from the surface; in many embodiments of the invention, signals are received from two separate points. The signals received are passed to a synchronous phase detection system for analysis. The signals may be received at the same phase detector input and separated according to their expected time of receipt relative to their time of transmission, or they may be received at separated points on the transducer related to their separated points of transmission. The separated return signals are compared on the basis of phase (and in certain embodiments, magnitude) differential either to each other or to an internally generated reference signal to analyze the surface characteristics of the material.
    • 一种声学显微镜,包括用于向待研究的表面传送声学信号的换能器,以及用于从所述表面接收至少一个反射信号的装置; 在本发明的许多实施例中,从两个分开的点接收信号。 接收到的信号被传递到同步相位检测系统进行分析。 信号可以在相同的相位检测器输入处接收,并根据其相对于其传输时间的预期接收时间分离,或者它们可以在与其分离的传输点相关的传感器上的分离点处被接收。 基于相位(和在某些实施例中的幅度)差分彼此或与内部产生的参考信号对分离的返回信号进行比较,以分析材料的表面特性。

    • Method and apparatus for thermoacoustic or thermal wave microscopy to detect surface and subsurface information from a material on a microscopic scale. A thermal wave is generated in a material by causing periodic, localized heating at a microscopic spot by focusing intensity modulated light, or electromagnetic radiation or particle beam, on the spot. The thermoacoustic signal produced provides information about material composition, structure, and the presence of energy deexcitation processes such as fluorescence, photochemistry and photovoltaic processes. The sample is scanned as a two-dimensional array of microscopic spots. Full depth-profiling of the material is provided by varying the modulation frequency of the energy source.
