| 摘要 |
We describe a holographic image projector, comprising: a laser light source to provide light at a laser wavelength; a first spatial light modulator (SLM) to display a hologram, wherein said first SLM is illuminated by said laser light source; intermediate image optics to provide a first intermediate real image plane at which a real image produced by said hologram displayed on said first SLM is formed; a wavelength-conversion material located at said first intermediate real image plane to convert said laser wavelength to at least a first output wavelength different to said laser wavelength; and second optics to project light from said real image at said output wavelength to provide a displayed image. |
