The system diagram. (A) The whole system can be divided into three sections according to their functions. These three sections of the system are operated in sequence and work independently. (B) The figure shows the experimental setup of back-reflection polarization states analyzing system. The polarization states generator (PSG) is composed of a laser diode with 850 nm wavelength, one linear polarizer, and two waveplates. The light escaping from the PSG is then focused to obtain single-spot data on the sample, which is collected by the detector. LP: linear polarizer. HWP: half waveplate. QWP: quarter waveplate.
