3-dhimensional electric field visualization utilizing electric-field-induced-second harmonic-generation in liquid crystals

摘要

Figure 3 shows an example of the EFISHG xyimages taken from a CCD in the scanning SHG microscope on the test sample shown in Figure 1. The incident direction of the laser was along the z-axis in figure 1. The polarization of the laser was along the gap that was perpendicular to the electric field. The two images with the same intensity scales show the difference of electric field in different z positions. Figure 3 (a) was taken at the plain of the electrodes, while figure 3 (b) was taken at 5 μm higher than (a). With the great sectioning power in confocal microscope, 3D images can be easily obtained combining different height images. More data will be presented including 3D images.
