Abstract
A two-dimensional holographic image projection display method. The method includes illuminating a first modulating part of a spatial light modulator with a first incident light beam at a first incident angle with respect to a direction normal to a main surface of the spatial light modulator to form a first projection region on an imaging plane; and illuminating a second modulating part of the spatial light modulator with a second incident light beam at a second incident angle with respect to the direction normal to the main surface of the spatial light modulator to form a second projection region on the imaging plane. The first projection region abuts or partially overlaps with the second projection region at an interface substantially parallel to a lateral direction of the spatial light modulator.
