Paper Abstract

We developed a compact polarization-converter using two liquid-crystal spatial-light-modulators with eight electrodes. The converter converted a linearly polarized beam to two orthogonal linearly polarized beams and a radially polarized beam, and the direction of the electric filed at the focal point were controlled three-dimensionally. We constructed a second-harmonic-generation microscope using the polarization-converter to observe three-dimensional molecular orientation and demonstrated the detectability of molecular orientation.
