Likewise, optical activity for the (001) plane was studied by using a conventional polarimeter in the same temperature range at 632.8 nm wavelength. In the latter case, a modulation of the optical activity was observed. Polarization measurement is generally performed in scenes with a low signal-to-noise ratio (SNR) such as remote sensing and biological tissue detection. The spatially modulated polarimeter can satisfy the real-time measurement requirements in low SNR scenes by establishing the mapping between photon spatial distribution and polarization information. .However, the accuracy of absolute polarimetric calibration strongly depends on the polarimeter design and observing conditions, which results in largely unknown systematic errors hindering the exoplanet polarization detection. . {High-precision and high-accuracy polarimetry of exoplanets}, author={Andrei Berdyugin and Svetlana V.
