Method and device for achieving optical spatial phase modulation |
| 摘要 |
Optical spatial phase modulation is achieved by positioning a liquid crystal layer in the path of a light beam to be modulated and controlling the spatial distribution of refractive index of the liquid crystal layer by controlling the spatial distribution of the electrical field generated across the liquid crystal layer.
