  In the apparatus of Reference Example 1, the imaging position of the CCD 152 has been manually adjusted with respect to the imaging plane error due to chromatic aberration. For this reason, it is necessary to manually move the CCD 152 every time the spectral wavelength is changed.

  However, in actual measurement, since the spectral wavelength is continuously changed and data is acquired, manual adjustment every time the spectral wavelength is changed, it takes a lot of time, and measurement conditions such as sunshine conditions change. It may end up.

  Therefore, an object of the present invention is to enable automatic adjustment of the imaging position of the CCD 152 with respect to an error of the imaging surface due to chromatic aberration.

  In the apparatus of Reference Example 1, since the CCD 152 moves only in the optical axis direction, the image position of the object to be captured at each polarization plane displacement angle can be changed by rotating the LCTF 132 and changing the polarization plane displacement angle of the incident light. There is a problem that the image is different, the orientation of the image of the object to be captured cannot be adjusted, and the image cannot be captured in a horizontal relationship with the object, and the present invention aims to solve these problems.

The filter driving device 131 is operated to rotate the filter 130. Further, the obtained polarization plane displacement angle is output to the sensor control unit 230 (S102).

  The sensor control unit 230 receives the wavelength from the filter voltage control unit 210, and acquires the drive amount for the input wavelength from the wavelength drive amount storage unit 293. Further, the polarization plane displacement angle is input from the filter rotation control unit 220, and the drive amount for the input polarization plane displacement angle is acquired from the displacement angle drive amount storage unit 294 (S103).

  The sensor control unit 230 generates a pulse for the drive amount acquired from the wavelength drive amount storage unit 293 to operate the sensor drive device 160 to move the image sensor 150 in the optical axis direction of the incident light. Further, the sensor driving device 160 is operated by generating pulses for the driving amount acquired from the displacement angle driving amount storage unit 294, and the image sensor 150 is moved on a plane intersecting the optical axis of incident light (S104).

The filter rotation control unit 220 determines whether the displacement angle storage unit 292 stores other polarization plane displacement angles that are intended to be filtered by the filter 130 (S106).
If another polarization plane displacement angle is stored as a result of the determination in S106, the filter 130 is rotated by the rotation amount with respect to the polarization plane displacement angle, and the image sensor is driven by the drive amount with respect to the polarization plane displacement angle. Image data is acquired and stored, and the determination of the presence or absence of another polarization plane displacement angle is repeated (S102 to S106).

If no other polarization plane displacement angle is stored as a result of the determination in S106, the filter voltage control unit 210 stores in the voltage wavelength storage unit 291 other types of wavelengths that are to be filtered by the filter 130. Determination is made (S107).
