Abstract
The light control device includes a light modulation module and a dispersion compensation module. The light modulation module is used for modulating an incident light field to obtain a target diffraction light field. The dispersion compensation module is used for performing dispersion compensation on the target diffraction light field, so that light fields having different wavelength in the target diffraction light field have the same spatial location distribution, or the light fields having different wavelength in the target diffraction light field have the same spatial angle distribution.
