The polarization filter electrically controls the pattern of polarization filtering. Since the polarization of the fluorescence from a single molecule highly depends on the angle between the observation direction and the molecular direction, polarization pattern filtering at the pupil plane of the objective lens allows the orientation of a single molecule to be visualized. Using this system, we demonstrated the orientation detection of single molecules. 收起
