A holographic light-emitting module includes a light source module and a light shape control module. The light source module is configured to provide a signal light beam and a reference light beam, in which polarizations of the signal light beam and the reference light beam are orthogonal. The light shape control module is configured to receive the signal light beam and the reference light beam propagated from the light source module, in which the signal light beam and the reference light beam are modulated and emitted by the light shape control module The reference light beam is surrounded by the signal light beam and located at a center of the signal light beam, and the signal light beam and the reference light beam are partially overlapped.
