| 摘要 |
A measurement apparatus includes a polarization controller which controls polarization of light, a wavefront dividing unit which divides a wavefront of the light, a polarizing unit which polarizes the light, a detector which detects the light, a first driving unit which moves the wavefront dividing unit with respect to the detector, a second driving unit which moves the polarizing unit with respect to the detector, and a processor which calculates the optical characteristics of the detection target using a detection results obtained when the wavefront dividing unit is positioned in the optical path and a detection result obtained when the wavefront dividing unit is positioned outside the optical path.
