    • A cantilever has a probe on one side of the end portion and a mirror on the opposite side. The cantilever is fixed to a support member via a piezoelectric element. A semiconductor laser situated above the mirror has a reflection cleavage plane and constitutes a Fabry-Perot resonator between the mirror and the reflection cleavage plane. The output from the resonator varies in accordance with the amount of displacement of the end portion of the cantilever, that is, the surface configuration of the sample. This variation is detected by a detector via a photodetector. A control circuit controls a driving voltage applied to an XYZ-scanner so as to cancel the variation of the output from the resonator, thereby keeping constant the distance between the tip of the probe and the surface of the sample. The driving voltage provides height data of the sample surface. The driving voltage, along with a position signal relating to the sample surface output from the XYZ-scanner, is supplied to an image forming unit. The image forming unit generates a three-dimensional image representing the surface configuration of the sample, on the basis of the input voltage and signal.
    • 悬臂在端部的一侧具有探针,在相对侧具有反射镜。 悬臂通过压电元件固定到支撑构件上。 位于反射镜上方的半导体激光器具有反射解理面,并且在反射镜和反射解理面之间构成了法布里 - 珀罗(Francry-Pérot)谐振器。 谐振器的输出根据悬臂的端部的位移量,即样品的表面构型而变化。 该变化由检测器通过光电检测器检测。 控制电路控制施加到XYZ扫描仪的驱动电压,以抵消来自谐振器的输出的变化,从而保持探针的尖端与样品表面之间的距离恒定。 驱动电压提供样品表面的高度数据。 驱动电压以及与从XYZ扫描器输出的样品表面相关的位置信号被提供给图像形成单元。 图像形成单元基于输入电压和信号生成表示样本的表面配置的三维图像。

    • A light source generates probe light to be radiated on a sample. An optical probe has a pin hole at its distal end and selectively supplies the probe light to the sample through the pin hole. An optical detecting unit detects light emerging from the sample and converts it to an electrical signal. The light source generates the probe light whose intensity changes in the pulse-like manner. The optical detecting unit detects the light emerging from the sample in synchronism with an increase in probe light which changes in the pulse-like manner and converts it to the electric signal. Therefore, noise which is conventionally converted to an electrical signal can be decreased even when the probe light which changes in the pulse-like manner is decreased, and measurement can be performed at a high S/N ratio even if the pin hole diameter is small. As a result, the resolution of a near field scanning optical microscope can be improved.
    • 光源产生要照射在样品上的探测光。 光学探针在其远端具有针孔,并通过针孔选择性地将探针光提供给样品。 光学检测单元检测从样品发出的光并将其转换成电信号。 光源产生其脉冲状强度变化的探测光。 光检测单元与脉冲状方式变化的探测光的增加同步地检测从样本出射的光,并将其转换为电信号。 因此,即使当脉冲状变化的探测光减少时,也可以降低传统上转换为电信号的噪声,即使针孔直径小,也可以以高S / N比进行测量 。 结果,可以提高近场扫描光学显微镜的分辨率。
