Abstract
A holographic projector includes a spatial light modulator, a light receiving member and a driver. The spatial light modulator is arranged to receive and represent a computer-generated hologram and spatially modulate light incident on the spatial light modulator to form a holographic reconstruction in accordance with the computer-generated hologram. The light receiving member is arranged to receive spatially modulated light along an optical axis from the spatial light modulator and the holographic reconstruction is formed on the light receiving member. The driver is coupled to the light receiving member to move the light receiving member in a plane. The driver is configured to move the light receiving member while maintaining an orientation of the light receiving member relative to the spatial light modulator substantially constant.
