Abstract

[Problem] To provide a confocal displacement meter which is capable of easily and accurately measuring the displacement of a measurement object. [Solution] Light having chromatic aberration is made to converge by a lens unit (220), and a measurement object (S) is irradiated therewith from a measurement head (200). Light of wavelengths reflected by the surface of the measurement object (S) while focusing passes through an optical fibre (314) in the measurement head (200). The light that has passed through the optical fibre (314) is guided to a light dispersion unit (130) in a processing device (100), and dispersed. In the processing device (100), the light dispersed by the light dispersion unit (130) is received by a light reception unit (140), and a light reception signal outputted from the light reception unit (140) is acquired by a control unit (152). The control unit (152) measures displacement on the basis of the acquired light reception signal, and delivers the light reception signal to an external PC (600). A CPU (601) of the PC (600) displays, as change information, on a display unit (700), the change from the light reception signal acquired at a time point before the current time point, to the light reception signal acquired at the current time point.

Abstract

[Problem] To provide a confocal displacement meter capable of reducing measurement error. [Solution] Light of a plurality of wavelengths is emitted by a light projection unit (120). A lens unit (220) is used to generate, in the light emitted by the light projection unit (120), chromatic aberration along the optical axis direction. Furthermore, the light having chromatic aberration is made to converge by the lens unit (220), and a measurement object (S) is irradiated therewith. Light of wavelengths reflected by the surface of the measurement object (S) while focusing, among the light with which the measurement object (S) is irradiated via the lens unit (220), passes through a plurality of pin holes. Displacement of the measurement object (S) is calculated by a calculation processing unit (150), on the basis of the signal intensity of each wavelength of an average signal corresponding to the average intensity of each wavelength of the plurality of rays of light which have passed through the plurality of pin holes.

Abstract

[Problem] To prevent mixture of a model member and a support member at an interface. [Solution] A control means causes a head part (20) to perform a reciprocating scanning in one direction by a horizontal driving means and causes a shaping member discharging means to discharge a model member (MA) and a support member (SA) onto a shaping plate (40). The model member (MA) and/or the support member (SA) are cured by a curing means (24) in at least one of inbound and outbound of the reciprocating scanning to make a slice. Relative positions of the shaping plate (40) and the head part (20) are moved in a height direction to repeat lamination of the slices so that the device is controlled to perform shaping. Also, only one of the model member (MA) and the support member (SA) can be discharged and cured instead of discharging both of the shaping members in the same reciprocating scanning in a line where the model member (MA) and the support member (SA) in a scanning direction of a shaped object are located.
