Abstract:
To provide a confocal displacement sensor capable of reducing a measurement error. Light having a plurality of wavelengths is emitted by a light processing section  120.  A chromatic aberration along an optical axis direction is caused by a lens unit  220  in the light emitted by the light projecting section  120.  The light having the chromatic aberration converged and irradiated on a measurement object S by the lens unit  220.  In the light irradiated on the measurement object S by the lens unit  220,  light having a wavelength reflected while focusing on the surface of the measurement object S passes through a plurality of pinholes. Displacement of the measurement object S is calculated by an arithmetic processing section  150  on the basis of signal intensity for each wavelength of an average signal corresponding to an average of intensities for each wavelength concerning a plurality of lights passed through the plurality of pinholes.

Claim (Index 1):
A confocal displacement sensor that measures displacement of a measurement object using a confocal optical system,\n the confocal displacement sensor comprising: a light projecting section configured to emit light having a plurality of wavelengths; an optical member configured to cause a chromatic aberration along an optical axis direction in the light emitted by the light projecting section, converge the light having the chromatic aberration, and irradiate the light on the measurement object; a pinhole member including a plurality of pinholes that allow, in the light irradiated on the measurement object by the optical member, light having a wavelength reflected while focusing on a surface of the measurement object to pass; and a displacement measuring section configured to calculate the displacement of the measurement object on the basis of signal intensity for each wavelength of an average signal corresponding to an average of intensities for the each wavelength concerning a plurality of lights passed through the plurality of pinholes.
