ABSTRACT:
An image projecting device and method are presented. The device comprises a light source system, a spatial light modulator (SLM) unit, and an image projection optics accommodated at the output side of the SLM unit. The SLM unit may be reflective or transmissive. The SLM unit comprises an SLM pixel arrangement enclosed between two glass substrates. The pixel array arrangement is formed by a pixel array assembly and at least one microlens assembly. The microlens assembly includes at least one microlens array accommodated proximate of the pixel array assembly. The light source system may comprise n light sources and a light converting means in optical path of light generated by the n light sources, to thereby produce m light beams of different wavelength ranges, wherein m>n. The light source system may comprise a multi-mode laser, thereby reducing a speckle effect in an integrated speckle pattern produced by the multiple modes, as compared to that of a single mode.
