摘要： The present invention provides a method of using an accurate three-dimensional shape without damaging a sample by making a probe contact the sample only at a measuring point, lifting and retracting the probe when moving to the next measuring point and making the probe approach the sample after moving to the next measuring point, wherein high frequency/minute amplitude cantilever excitation and vibration detection are performed and further horizontal direction excitation or vertical/horizontal double direction excitation are performed to improve the sensitivity of contacting force detection on a slope of steep inclination. The method uses unit for inclining the probe in accordance with the inclination of a measurement target and a structure capable of absorbing or adjusting the orientation of the light detecting the condition of contact between the probe and sample after reflection on the cantilever, which varies a great deal depending on the inclination of the probe.

摘要： In a displacement measurement apparatus using light interference, a probe light path is spatially separated from a reference light path. Therefore, when a temperature or refractive index distribution by a fluctuation of air or the like, or a mechanical vibration is generated, an optical path difference fluctuates between both of the optical paths, and a measurement error is generated. In the solution, an optical axis of probe light is brought close to that of reference light by a distance which is not influenced by any disturbance, a sample is irradiated with the probe light, a reference surface is irradiated with the reference light, reflected light beams are allowed to interfere with each other, and a displacement of the sample is obtained from the resultant interference light to thereby prevent the measurement error from being generated by the fluctuation of the optical path difference.

摘要： It is difficult for a scanning probe microscope according to the conventional technology to operate a probe for scanning and positioning in a wide range and for high-precision scanning in a narrow range. A scanning probe microscope according to the invention uses probe driving actuators for coarse adjustment and fine adjustment. For scanning and positioning in a wide range, the coarse adjustment actuator is switched to fast responsiveness. For scanning in a narrow range, the coarse adjustment actuator is switched to slow responsiveness. Instead, positional noise is reduced and the fine adjustment actuator is mainly used for scanning in a narrow range. The probe is capable of not only scanning and positioning in a wide range but also high-precision scanning in a narrow range.

摘要： In a near-field scanning microscope using an aperture probe, the upper limit of the aperture formation is at most several ten nm in practice. In a near-field scanning microscope using a scatter probe, the resolution ability is limited to at most several ten nm because of the external illuminating light serving as background noise. Moreover, measurement reproducibility is seriously lowered by a damage or abrasion of a probe. Optical data and unevenness data of the surface of a sample can be measured at a nm-order resolution ability and a high reproducibility while damaging neither the probe nor the sample by fabricating a plasmon-enhanced near-field probe having a nm-order optical resolution ability by combining a nm-order cylindrical structure with nm-order microparticles and repeatedly moving the probe toward the sample and away therefrom at a low contact force at individual measurement points on the sample.
