    摘要： The invention provides a fine-adjustment mechanism for a scanning probe microscopy with high rigidity and high degree of measurement accuracy wherein a strain gauge displacement sensor which can be installed in a small space is arranged so that temperature compensation is achieved. The fine-adjustment mechanism composed of a piezoelectric device is provided with at least two-piece electrode. One of the electrodes is configured as a dummy electrode, to which no voltage is applied, and the other electrode is configured as an active electrode which generates strain when voltage is applied. One or two resistors are provided on each of the active electrode and dummy electrode, and a bridge circuit is configured by the resistors.

    摘要： The optical displacement-detecting mechanism has: a light source for irradiating a target for measurement with light; a light source-driving circuit for driving the light source; an optical detector made from a semiconductor for receiving light after the irradiation of the target for measurement by the light source and converting the light into an electric signal thereby to detect an intensity of light; and an amplifier including a current-voltage conversion circuit for performing current-to-voltage conversion on a detection signal of the optical detector with a predetermined amplification factor. In the optical displacement-detecting mechanism, a light source having a spectrum half width of 10 nm or larger is used, whereby the light source can be driven with an output power of 2 mW or larger without generating mode hop noise and optical feedback noise.
