A device for measuring a large-area and massive scattered field in nanoscale. The device includes a polarization state generator disposed on an output optical path of a laser source, a polarization state analyzer operating to demodulate a polarized light beam emitted thereon, a first objective lens and a first lens disposed on an optical path of a sample stage, and a scanning mirror disposed on an optical path in front of or at the rear of the polarization state generator.

Method and device for measuring large-area and massive scattered field in nanoscale

An alignment method for optical axes of a composite waveplate includes rotating a rotatable waveplate, which rotates about a central axis with respect to a fixed waveplate, and adjusting the rotation angle thereof until the differences between the spectral parameters of the composite waveplate and ideal spectral parameters are smaller than preset values.
