Abstract
The present disclosure provides an optical modulation device, an optical modulation method and a holographic display apparatus. The optical modulation device is configured to perform optical modulation of a light beam and comprising: an amplitude modulator, configured to perform amplitude modulation of the light beam based on amplitude information in complex amplitude information of each pixel of a digital hologram; an optical scanning assembly, configured to scan the light beam within a predetermined range; a phase modulator, configured to perform phase modulation of the light beam based on phase information in the complex amplitude information.
