    摘要: There is provided an optical displacement detection mechanism in which, even if a measurement object changes, a detection sensitivity and a ratio of a noise are adjustable without depending on optical characteristics such as reflectivity, or a shape and mechanical characteristics of a measurement object, an influence of a thermal deformation of the measurement object by an irradiated light to the measurement object can be made small, and a measurement accuracy can be ensured under optimum conditions. In an optical displacement detection mechanism comprising a light source irradiating a light to a cantilever becoming the measurement object, a light source drive circuit driving the light source, a photodetector receiving the light after irradiated to the cantilever from the light source to thereby detect an intensity of the light, and an amplifier amplifying a detection signal of the photodetector at a predetermined amplification rate, there is made such that, by providing a light intensity regulator and an amplification rate regulator, an irradiated light intensity to the cantilever and an amplification rate of the photodetector can be made variable.

    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.
