A pulsed beam is split into two; one beam is reflected by an object under measurement and then inputted to a delay optical path equivalent to one pulse period; and the other beam is sent through the same delay optical path in the opposite direction up to the object under measurement with a delay of one pulse period, and then reflected by the object under measurement. An optical phase variation caused by the movement of the object under measurement is obtained by subjecting the two pulsed beams to interference.

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： 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.
