Image processing by nonlinear Fourier transformation optical system possessing a dye-doped liquid crystal

摘要

Dye-doped liquid crystals in the mesophase have been exhibit extremely large laser-induced refractive index change originating in various mechanisms, including photothermal, photochemical reaction, optical electric field, and photo-induced space charge field. In this study, we demonstrated optical image processing by means of nonlinear Fourier transformation system possessing the dye-doped liquid crystals.
